IntroductionIn response to frequent requests from our retail clients we have developed the Good Health Products’ Natural Health Course.
The course is user friendly and informative. It will help increase your knowledge and understanding of the workings of the human body, what can go wrong and what can be done to help.
It comprises four modules: Module 1 | Digestive system Module 2 | Nervous and cardiovascular systems Module 3 | Musculoskeletal, lymphatic and immune systems Module 4 | Urinary and reproductive systems
The modules explain the major workings of each system, what common health problems can arise, their signs and symptoms, causes, treatment suggestions and the relevant Good Health products to recommend.
For people with good knowledge it will be a great refresher, but for those who are new to the industry, it will be an exciting learning tool.
Each module contains a set of questions for you to answer in your own time. The questions are directly related to the notes. No other reference books are required.
Disclaimer: The information in this course provides an introduction into medical and health care issues and is not designed to replace medical recommendations or a full consultation with a health professional. We strongly recommend individuals discuss on-going or serious health issues with their health care provider.
Author: Jenni LaneJenni became interested in the natural health field as a teenager after reading Leslie Kenton’s books and she quickly learned how good it felt when she ate healthy foods and exercised regularly. This lead to further investigation on how to improve her health using natural remedies, and so the journey began.
In her early twenties she traveled extensively overseas living in both London and California. Eventually she was drawn back to New Zealand to study natural medicine.
Jenni obtained a Bachelor of Science from Canterbury University, majoring in Zoology, then a Bachelor of Health Science from Charles Sturt University, for which she received a Dean’s Award for academic excellence. She also received Advanced Diplomas in both Naturopathy and Herbal Medicine from South Pacific College of Natural Therapeutics in Auckland.
Jenni began her role at Good Health as an in-store naturopath. She then moved into the marketing team specialising in providing technical information, research and product development, scientific validation, educational training and health advice on the 0800 Naturopathic adviceline.
Jenni ran a successful private naturopathic clinic in Auckland for two years prior to joining Good Health’s naturopathic team.

GoalThe goal of Module two is to begin understanding our complex nervous system. We will cover everything from the intricate workings of our brain, through to the nerve cells and how they function in our body. We will also address common conditions that affect our nervous system and how to treat them.
The second system of this module is the cardiovascular system. We will look at the functions, components and the transport vessels of our blood and our heart - the pump that keeps our blood flowing from the top of our head to the tips of our toes. We will then examine what can go wrong with our heart, blood and blood vessels and how to keep them in good health.

Part one: The nervous systemANATOMY AND PHYSIOLOgY HOW IT WORkS
1. Functions of the nervous system• To provide control and communication between all
body systems• Involved in all individual behaviours; including every
thought, action and emotion• Processes information from all sensory perception
and transmits it to the appropriate body systems• Works in union with the endocrine (hormonal) system
to provide integration throughout the entire body
2. Structure of the nervous system
Cells of the Nervous System • Nerve tissue is made up of two types of cells: a. Neurons – the cells that conduct nerve
transmission b. Supporting cells – comprised of glial cells in the
CNS and Schwann cells in the PNS; these cells assist the function of neurons
CENTRAL NERVOUS SYSTEM (CNS)
The central nervous system is comprised of: • The brain • The spinal cord
3. The brainThe brain is comprised of three main areas: (see diagram 1)• Cerebrum - this is the largest and most advanced
part of the brain. It controls all conscious behaviours. • Cerebellum – we are not consciously aware of
the workings of the cerebellum but it is known to streamline our movements
• Brain Stem – controls unconscious actions such as breathing, heart rate and blood pressure
Diagram 1: The main regions of the brain
Cerebrum• The largest part of the brain, accounting for about
83% of the total brain mass • Composed of 2 distinct hemispheres. It has a
convoluted appearance with many fissures (grooves), giving the brain a wrinkled look. (See diagram 2)
• Main regions of the cerebrum include: - Frontal lobe - Occipital lobe - Parietal lobe - Temporal lobe - Right Hemisphere - Left Hemisphere - Corpus callosum
Diagram 2: Regions of the Cerebrum
Functions of the regions within the Cerebrum:Frontal lobe:• Behaviour, thought, intellect, judgement
nervous and cardiovascular systems 5
module two
• Problem solving, initiative• Some emotions, coordination of movements• Eye movements, sense of smell, muscle movements• Libido, skilled movements
Occipital lobe:• Vision• Reading
Parietal lobe:• Sense of touch• Response to internal stimuli• Sensory comprehension (understanding what we
see, hear, feel etc.)• Some language and reading functions• Some visual functions
Temporal lobe:• Auditory memories, some hearing, visual memories• Music, fear, some language, some speech• Some behaviour and emotions, sense of identity
or self
Right hemisphere:• Controls the left side of the body• Temporal and spatial relationships• Analysis of non-verbal information• Communicating emotion
Left hemisphere:• Controls the right side of the body• Produces and understands language
Corpus callosum:• Provides communication between the left and right
side of our brain
Cerebellum• Accounts for approximately 11% of the total brain
mass• We have no actual awareness of the workings of the
cerebellum as it functions subconsciously• Processes information from the motor region of the
frontal lobe and brain stem to make movements smoother, more coordinated and precise
• Facilitates balance and posture
Brain stem• Comprised of the Medulla and the Pons • Controls essential involuntary functions such as
breathing, heart rate and blood pressure• Provides a pathway between the brain and the spinal
cord• Provides additional motor and sensory pathways to
the face and body
Other structures within our brain• The limbic system is composed of the thalamus and
hypothalamus. These structures work together to modulate our emotions.
• The reticular formation is a network of nerves that run through the brain stem and thalamus and filter incoming sensory impulses to prevent brain overload, enabling us to sleep
• A theory exists that in children with ADD or ADHD this mechanism is less efficient therefore their brains are bombarded with sensory information, which in turn affects their behaviour
Protection of the Central Nervous System (CNS)• The nervous system tissue is very delicate and
can be damaged easily by head injuries, alcohol, pesticides and toxins (more reason to eat organic food), or a lack of oxygen
• Antioxidants are nutrients that help protect brain cells• The brain and spinal cord are enclosed within strong
bony structures that provide rigid protection. The skull protects the brain and the spine protects the spinal cord.
• Further protection for the brain is provided by the cushioning effect of the cerebrospinal fluid (special fluid found around the brain and spinal cord) and tough connective tissue membranes - the meninges
• The blood-brain barrier prevents toxins, fluctuating hormones, amino acids or chemical ions that may be present in the blood from entering the brain
4. Spinal cord • The spinal cord extends down from the base of the
skull through the spine to the upper lumbar regions (lower back)
• It is a thick, white band of nervous tissue that provides a two-way conduction pathway between the brain and the rest of the body
• Many spinal reflexes can independently activate complex motor activities such as those performed when walking or dancing
• Large spinal nerve roots called horns exit the spinal cord to form the peripheral nervous system
5. Peripheral nervous system (PNS)• The PNS provides a valuable link between the
outside world and the brain. It consists of all nerve tissue outside the CNS.
• The PNS is divided into the a. Somatic nervous systems b. Autonomic nervous systems• The Somatic nervous system is made up of nerves
that connect skeletal muscles. They initiate voluntary movement (motor) and sensory perception.
• The Autonomic nervous system is involuntary and
6 www.goodhealth.co.nz
connects nerves from the CNS to cardiac muscles (heart), smooth muscles (surrounding arteries and organs), and glands
a. Somatic Nervous System• The somatic nervous system is comprised of two
types of nerves - sensory and motor i) Sensory nerves carry information to the brain ii) Motor nerves carry information away from the brain• Most nerve bundles are made from a combination of
sensory and motor nerves. They exit and enter the spinal cord in the form of spinal nerves.
(See diagram 3)• Large groups of nerves form a plexus. The brachial
plexus exits between the bones of the cervical (neck) spine and supply nerves to the arms and hands.
• The lumbar plexus exits between the bones of the lumbar spine (lower back) including the nerves to the legs and feet. The largest nerve in the body is the sciatic.
• Injury to the lower back commonly causes sciatica - pain in the sciatic nerve, which runs down the back of the leg
Diagram 3: The spinal nerves exiting the spine
• The Sensory system has specialised receptors for receiving stimuli from outside the body. This can be in the form of heat, light (eyes), taste (chemicals on the tongue), touch or pain
• Over-stimulation of any receptor can cause pain • Proprioreceptors respond to stimuli within the body - They are located in skeletal muscles, tendons,
joints, ligaments and the tissue covering our muscles and bones
- These receptors monitor the body’s movements by measuring the degree of stretch in the muscles
• Motor nerves are involved in movement• They receive information from the brain and spinal
cord to send to the skeletal muscles
• These nerves control movement, balance and posture
• Nerve supply to the head goes via the cranial nerves, not via the spinal cord
• The cranial nerves allow movement of the eyes, tongue and facial muscles; enabling us to see, hear, eat and make facial expressions
b. Autonomic Nervous System• Consists of two divisions: a. Sympathetic b. Parasympathetic• These two divisions have opposing effects and
provide the nerve supply of both cardiac and smooth muscles, including the internal organs
• These two systems complement each other to help the body maintain balance
• The sympathetic nerves activate our body during severe circumstances such as fear, danger, anger, exercise and stress
• The parasympathetic nerves reverse the effects of the sympathetic system so the body’s responses return to normal
• The sympathetic and parasympathetic divisions are controlled by the hormones adrenaline and noradrenaline and the neurotransmitter acetylcholine
• Understanding these systems highlights how we digest food more efficiently when we are relaxed and how stress can affect our health
Sympathetic Nervous SystemStimulation of this system is often referred to as the
‘fight or flight’ response. This prepares the body for an emergency and enables us to respond physically, see clearly and think decisively.
It does this by:• Stimulating the adrenal glands to produce the stress
hormones adrenaline and noradrenaline• Increasing perspiration• Dilating the pupils• Causing the hair follicle muscles to erect producing
‘goose bumps’• Increasing the rate and force of the heartbeat• Inhibiting urination• Dilating bronchioles within the lungs to increase
oxygen intake• Decreasing the activity and blood flow of the
digestive tract • Redirecting blood flow to the skeletal muscles, heart,
brain and lungs• Stimulating the liver to release glucose for increased
energy levels• Constricting most blood vessels and increasing
blood pressure
nervous and cardiovascular systems 7
module two
Cell body:• The cell body is usually spherical in shape and
contains the cell organelles and nucleus (containing the genetic material)
• The main metabolic activities of a nerve cell take place within the cell body
• Most neurons have their cell body within the brain or spinal cord (CNS) where they are protected by the bones of the skull or spine
Axon:• Each neuron has a single axon that may be very
short or very long. For example, the axon that activates the muscle in the big toe originates from the cell body in the lumbar area of the spinal cord.
• A long axon such as the one described, is known as a nerve fibre
• The axons are the functional (working) structures involved in nerve conduction. Axons carry information away from the cell body
Dendrites:• Dendrites are generally multi-branched extensions of
the cell body. Their function is to receive information and conduct it to the cell body.
• They can also communicate with dendrites and axons of other cells
Supporting cells• These cells enable the neurons to function efficiently.
They segregate and insulate the neurons to avoid interference from other nerve impulses.
a) Neuroglia (glial cells):• This is the collective term for all supporting cells
within the CNS• Neuroglia are smaller than neurons and outnumber
them by 9:1. They make up approximately half the brain.
• Some functions of glial cells: - Glial cells act as immune presenting cells - Rebalance electrical ion levels surrounding
the neurons - Help clean up any damaged nerve cells or
invading micro-organisms - Help circulate cerebrospinal fluid - Provide an insulating barrier around axons to
aid electrical transmission. This barrier is known as the myelin sheath.
b) Satellite and Schwann cells• These are the supporting cells of the PNS• They have similar functions to the glial cells of
the CNS• The Schwann cells surround the nerve fibres to form
Parasympathetic Nervous System:• The parasympathetic nervous system acts to return
the body to its normal balanced state • This system is most active during non-stressful
periods and is known as the ‘resting and digesting’ division
• The parasympathetic nervous system is designed to conserve energy, promote digestion and stimulate the elimination of faeces and urine
It does this by:• Increasing gut motility, digestive secretions and
relaxing sphincters• Constricting the pupils• Improving close-up visual acuity• Decreasing heart rate, therefore promoting a slow
and steady heart beat• Relaxing the urethral sphincter to promote urination• Constricting the bronchioles within the lungs
6. Nerve tissue structureNerve tissue is highly complex and densely compacted. It is comprised of two main types of cells:• Neurons – cells that transmit electrical signals• Supporting cells – smaller cells that surround the
delicate neurons
Neurons a. Neurons, or nerve cells, are the highly specialised
units that conduct electrical messages via nerve impulses
b. They also have other distinctive characteristics: - Longevity - providing they receive adequate
nutrition, neurons can live for over 100 years - They are unable to divide once they are mature,
therefore once destroyed they cannot be replaced - Neurons have a very high metabolic rate, and
therefore need a continuous supply of oxygen and glucose
- They are generally quite large and complex cells (See diagram 4)
Neurons are comprised of a cell body, an axon and dendrite

Part two: The nervous systemWHAT CAN gO WRONg
1. Attention deficit disorder (ADD) & Attention deficit and hyperactivity disorder (ADHD)
Signs and symptoms• Inattention and/or poor concentration• Easily distracted or easily bored• Impulsive behaviour• Overactive or restless behaviour• Failure to finish tasks• Poor listening skills• Abrupt shifts of activity• Emotional and behaviour swings• Poor organizational skills• Learning difficulties• Disorders of memory and thinking• Affects approximately 5% of children• 50-60% of children will outgrow their symptoms by
the time they reach their 20’s or they will be better able to deal with the disorder
• Each child or adult will have his or her own set of unique symptoms
Causes• Brain injury• Essential fatty acid deficiency• Heavy metal toxicity e.g. lead, mercury, cadmium,
copper or aluminium• Food or food additive sensitivities and allergies• Environmental toxins• High carbohydrate or low protein diet• Thyroid disorders• Blood sugar fluctuations• Frequent ear infections or otitis media• Exposure to alcohol or drugs in utero• Impaired inhibitory mechanisms in the brain• Over-active limbic system in the brain creating
heightened vigilance and increased emotional outbursts
Treatment• Refer to a naturopath for testing of food allergies and
heavy metal toxicity• Common allergens include wheat, dairy products,
chocolate, oranges, eggs, peanuts and sugar. Keep these foods to a minimum as well as processed foods, artificial colouring, flavouring and preservatives.
myelin sheaths, which allow faster transmission of nerve impulses
• Inflammation of the Schwann cells occurs in Multiple Sclerosis (MS) and causes disruptions in nerve transmission
Nerve connections and transmission• Electrical and chemical signals are used by neurons
to communicate and transfer information around the body
• Each neuron can make as many as 10 000 contacts with other neurons
• That makes 1015 (10 with 15 zeros) nerve-to-nerve connections (doesn’t that make you feel brainy!)
The synapse• The synapse is the junction between neurons or
between a neuron and a gland; a neuron and an organ; or a neuron and a muscle that is being acted upon or influenced
• These synapses act as exchanges for ions or neurotransmitters (chemical messengers) between cells
Diagram 5: The synapse
• When a nerve impulse reaches the axon terminal, (Ca2+) calcium ions enter the cells and promote neurotransmitter release. Neurotransmitters then travel across the synapse and bind to the postsynaptic membrane receptors allowing the opening of the ion channel. This is short-lived because the neurotransmitter is destroyed or recycled and the channel closes. (See Diagram 5)
• Neurotransmitters can be classed as excitatory, inhibitory or both
• Nerves use synapses to communicate with muscles, causing them to relax or contract
• Alternatively, nerves communicate with organs, influencing them to secrete hormones or other neurotransmitters
nervous and cardiovascular systems 9
module two
• Avoid sugar, soft drinks and sugar-filled cordials• To prevent low blood sugar ensure the child has
regular protein filled meals• Ensure the child eats plenty of fresh organic
vegetables to improve nutrition• Eat wholegrains such as brown rice, oats and
millet because they are low glycaemic index (slowly absorbed) carbohydrates and full of nutrients
• Studies have shown a low allergy diet and additional nutritional supplements reduce ADD and ADHD behaviour
• Some children respond to osteopathic treatment• For children over two years of age add relaxing
essential oils to their bath – e.g. try adding Lavender, Chamomile or Lemon balm. Try herbal teas such as Chamomile, Lemon balm, Skullcap, Nettle or Oat straw. Cool and add fruit juice to improve the taste. Use at night to aid sleep or to calm down an overactive child.

Part three: The cardiovascular systemANATOMY & PHYSIOLOgYHOW IT WORkS
The Cardiovascular System is divided into three components:1. Blood2. Heart3. Blood vessels
1. Blood• Blood is the river of life and acts as the supreme
carrier of the sustenance each of our cells need. Since antiquity it has had a magical appeal as the
‘essence’ of life.• Blood is the vehicle of the cardiovascular system• The arteries carry oxygenated blood away from the
heart to the organs• The capillaries carry the blood to the tissues and
cells and then back to the veins• Veins carry deoxygenated blood back to the heart to
start the process again• Blood is a specialised type of connective tissue and
is made up of different components
The functions of blood• Distribution of: - Oxygen - Nutrients from the digestive system - Waste products to elimination organs - Hormones to their target organs• Regulation of: - Body temperature: by diverting blood to the skin
surface (reducing body heat) or keeping it to the core of the body (increasing body temperature)
- pH: blood components can act as buffers to prevent dramatic changes in acidity or alkalinity
• Protection from: - Blood loss: due to clotting factors - Infection: due to antibodies, complement proteins
and white blood cells, to defend our body
Components of blood• There are 2 main components of blood: - Plasma, the non-living fluid matrix - Red and white blood cells
Plasma• 90% of plasma is water
14 www.goodhealth.co.nz
Destruction of RBCs• After 100 – 120 days the RBCs become rigid, fragile
and their haemoglobin begins to deteriorate• They are destroyed in the spleen and the iron is
stored for future use• The heme group is broken down into bilirubin that is
released into the blood to be picked up by the liver and excreted through bile into the faeces
White Blood Cells (WBCs)• These account for only 1% of the total blood volume• They form part of the immune or defence system• They are able to leave the blood stream and enter
tissues as needed• We have five different types of WBCs: Neutrophils,
Lymphocytes, Monocytes, Eosinophils and Basophils (Never Let Monkeys Eat Bananas)
Neutrophils• Are the most numerous of the WBCs in the blood
and are involved with killing bacteria and fungi
Lymphocytes• Are the second most numerous WBCs and, as their
name suggests, are also found in lymphatic tissue
Types of lymphocytes• T lymphocytes act upon viral and cancer infected
cells• B lymphocytes produce antibodies to fight infectious
micro-organisms
Monocytes• These differentiate into specialised cells called
macrophages that are capable of engulfing bacteria and viruses. They also activate lymphocytes to mount an immune response.
Eosinophils• Their most important role is fighting parasitic
infections such as flatworms, tapeworms and flukes• They are also involved in allergic reactions
Basophils• These are the rarest WBCs in the blood stream and
are involved in inflammatory responses
Haemostasis (Blood stopping)• This is the process that occurs to prevent all our
blood leaking from our body if a breach of a blood vessel occurs
• It is a complex and well controlled process involving: - Vascular spasm - Platelet plug formation
• 8% of plasma is plasma protein; the most common plasma protein is albumin. It creates an important osmotic gradient (keeping water in the blood stream) and acts as a buffer.
• Other components include nutrients, hormones, waste products, antibodies, clotting factors and electrolytes
Red Blood Cells (RBCs)• These small flat disc-like cells have the important
function of transporting the gases, oxygen and carbon dioxide around the body
• Red blood cells are full of haemoglobin, which is the key oxygen and carbon dioxide carrying component of blood
• As oxygen deficient blood flows through the lungs, oxygen diffuses from the air sacs into the blood and red blood cells to bind with iron in haemoglobin and form oxyhaemoglobin. This gives blood its bright red colour.
• In the tissues the opposite occurs, oxygen detaches from the iron to diffuse into the cells and tissues. The molecule is now called deoxyhaemoglobin and the blood becomes a dark red colour.
• Carbon dioxide is carried around the body by the globin component of the haemoglobin and is carried to the lungs to be excreted via breathing
Production of Red Blood Cells• RBCs are formed within the red bone marrow of
some of the large or flat bones• To maintain healthy levels of RBCs, 2 million are
produced per second in healthy people!• The hormone erythropoietin stimulates the
production of RBCs• Men generally have higher numbers of RBCs than
women as testosterone enhances erythropoietin production. Premenopausal women lose RBCs through menstruation.
Nutrients required for healthy RBCs production
Iron• Iron forms part of the haemoglobin molecule where
oxygen binds• 65% of the body’s iron is found in haemoglobin,
while the rest is stored in our liver, spleen or in protein-iron complexes such as ferritin or hemosiderin
• Low iron levels cause a decrease in the size and number of RBCs
Vitamins• Vitamins B6 and B12 are essential for the DNA and
RNA involved in maturation and cell division of RBCs• Low levels of these B vitamins produce large, weak
RBCs with a shortened life span
nervous and cardiovascular systems 15
module two
Heart valves• The atrioventricular valves (bicuspid and tricuspid)
prevent the backflow of blood into the atria when the ventricles are contracting
• The pulmonary and aortic semilunar valves prevent back flow into the ventricles when they are relaxing
Blood flow to the heart• The heart muscle itself receives blood from the
coronary arteries, which branch off the aorta• These are the arteries that, when blocked, cause
angina or if severely blocked, heart attacks due to the obstruction of blood flow to the heart muscle
• Blood is delivered to the heart during the relaxation phase
• Venous blood from the heart is collected by the cardiac veins
Heart muscle cells• These cells are full of mitochondria (the energy
organelles within the cells) so have high requirements for oxygen
• The heart cells unlike other cells rely almost entirely on aerobic metabolism, so they cannot function optimally in low oxygen states. But, unlike nervous system cells, heart muscle cells can use fatty acids as a fuel as well as glucose.
• Heart cells work together as a unit to beat in a rhythmic and uniform way
• The heartbeat is controlled by specialised pacemaker cells, which are stimulated by the vagus nerve from the brain
Regulation of heart rate• The heart can pump 5 litres of blood per minute!• That’s a person’s entire blood volume through the
heart every minute
The heart rate can vary due to many factors:• Activation of the sympathetic nervous system due
to emotional or physical stress such as fear, anxiety, excitement or exercise increases the heart rate, due to the hormone adrenalin
• The heart is also affected by mineral concentrations in the blood. Changes in the concentrations of calcium, sodium, potassium or magnesium can affect heart muscle contractions and cause arrhythmia - an abnormal heart beat rhythm. Very high blood levels of sodium or very low levels of potassium can be life threatening.
• Other factors influencing heart rate include age, sex, exercise and body temperature
• Tachycardia is the term for an abnormally fast heart rate
• Bradycardia is the term for an abnormally slow heart rate
- Blood clotting - Repair of damage by fibrous tissue
2. The heart• The heart beats approx. 90 000 times per day and
we barely notice it• It is located behind the ribs and is about the size of a
clenched fist. It is surrounded by a special sac called the pericardium.
• The heart functions as two separate pumps• The right side pumps blood to the lungs for
oxygenation (pulmonary circulation)• The left side pumps blood to the whole body
(systemic circulation)
Diagram 6: The ventricles and valves of the heart
Pulmonary circulation• Deoxygenated blood from the systemic circulation
enters the right atrium of the heart (see diagram 6)• The blood then enters the right ventricle through the
tricuspid valve and is pumped into the lungs via the pulmonary arteries to receive oxygen
• This system is low pressure to allow the gradual diffusion of gases in the lungs
Systemic circulation• The oxygenated blood from the lungs enters the left
atrium via the pulmonary veins, and then enters the left ventricle to be pumped to the body via the large artery called the aorta
• The left side of the heart contains a larger muscular wall in order to pump the blood around the body to ensure the all parts of the body receive sufficient blood supply
• This is a high pressure system
16 www.goodhealth.co.nz
Diagram 7: The layers of the Blood Vessels
Arteries• Carry oxygenated blood away from the heart• Consist of strong, elastic walls to cope with the
pressure of blood coming directly from the heart• The ample amounts of elastin enable the arteries
to withstand this pressure and prevent pressure fluctuations. Thus the blood flows smoothly, although the blood is pulsated into the vessels by the pumping action of the heart.
• As the arteries branch and form arterioles the amount of elastin decreases and the amount of muscle in the tunica media increases and becomes more reactive to vasoconstriction and vasodilation
Capillaries• These are the finest and smallest vessels containing
only the tunica intima layer• They allow gas exchange in cells and tissues due to
their thin structure• Capillaries do not work independently but form
dense networks called capillary beds that make up the body’s microcirculation
Veins• Veins contain all 3 tunics but their walls are thinner
and the lumens are larger than the corresponding arteries due to a relatively lower blood pressure
• Veins contain much less smooth muscle and elastin in the tunica media
• Veins act as blood reservoirs and can hold as much as 65% of our total blood volume in capacitance vessels
• To prevent the backflow of blood, veins contain valves formed from folds in the tunica intima. They
• Congestive heart failure occurs when the heart is unable to pump enough blood to meet the demands of the body. This leads to a backflow of blood and consequent oedema (fluid) in the body or lungs.
• Atherosclerosis is the insidious build up and damage that occurs to blood vessels with age. If they become too blocked or damaged a heart attack or stroke can occur.
3. Blood vesselsThere are 3 main types of blood vessels:• Arteries• Capillaries• Veins
• Arteries are the large vessels that carry blood from the heart. These then branch into smaller arterioles and finally the very small capillaries.
• Blood then drains into venules, small veins and then large veins to be transported back to the heart
• This collection of blood vessels carries the blood around the body and if laid out would cover approx. 100 000km!
The Structure of Blood VesselsThey consist of three layers (tunics) surrounding a central space (lumen). (See diagram 7)• Tunica intima• Tunica media• Tunica adventitia(The exception is capillaries, which only contain the tunica intima)
Tunica intima • Is the inner most layer and consists of flat cells to
provide a slick surface for the blood to flow over
Tunica media• Contains layers of circularly arranged smooth muscle
and elastin• The smooth muscle is controlled by the autonomic
nervous system and can cause vasoconstriction - a narrowing of the lumen of the vessel, or vasodilation
- a widening of the lumen• These small changes in blood vessel diameter
influence blood flow and blood pressure• This is the largest layer due to the bulk of the smooth
muscle
Tunica adventitia• Is the outer most layer and consists of loose
collagen fibres to protect the vessel and anchor it to surrounding tissue
• Nerve fibres, lymphatic vessels and sometimes-tiny blood vessels can infiltrate this layer in arteries
nervous and cardiovascular systems 17
module two
centre in the brain, which monitors blood pressure• The vasomotor centre detects changes then dilates
or constricts the blood vessels, or alters heart rate to restore balance
Hormonal and chemical controlHormones that increase blood pressure by promoting vasoconstriction:a. Adrenalinb. Noradrenalinc. Anti-diuretic hormoned. Angiotensin II
Chemicals that decrease BP by promoting vasodilation:a. Atrial natriuretic peptideb. Nitric oxidec. Alcohol
Long-term control of Blood Pressure• The kidneys have a direct effect on the regulation of
blood pressure by monitoring blood volume• When the blood pressure rises, our kidneys can
excrete excess fluid by increasing urine output• When the blood pressure falls the kidneys retain fluid
and thus increase the blood volume• Falling blood pressure stimulates the kidneys to
release a hormone called renin, which triggers the formation of angiotensin II to stimulate vasoconstriction. Additionally, aldosterone is released promoting the retention of salt and water.
Blood pressure tends to rise as we age
Ideally the blood pressure should be below: Systolic - 130 mmHgDiastolic - 85 mmHgAnything above may indicate hypertension or high blood pressure.
Low blood pressure is considered normal in healthy individuals but can be a sign of poor nutrition (anaemia, low protein levels in the blood), disease, circulatory shock or extreme blood loss.
are especially valuable in the veins of the legs, to help counteract the downward pull of gravity.
• Respiratory and muscular pumps aid venous return to the heart
• The respiratory pump occurs due to pressure changes within the abdomen during breathing. The muscular pump occurs due to skeletal contractions
“milking” the blood back to the heart.
Blood pressure (BP)• Blood pressure is the force per unit area exerted on
the wall of a blood vessel by flowing blood• It is measured in mmHg (millilitres of mercury)• The systolic (top) reading measures the heart during
an active beat• The diastolic (bottom) is the reading during relaxation
(between beats)• 120 systolic and 80 diastolic is considered normal at
rest (120/80) mmHg• Blood always flows from high-pressure zones to
low-pressure zones, enabling the body to maintain perfusion to all tissue and allow blood to flow back to the heart
• The maintenance of our blood pressure is very important to ensure our organs have adequate blood supply to function correctly
Three factors that influence blood pressure 1. Cardiac output – the amount of blood pumped in
one minute2. Peripheral resistance – a measure of the amount of
friction encountered by blood as it flows through the blood vessels. Small changes in blood vessel diameter can have dramatic effects on blood pressure.
3. Blood volume – the amount of blood within the circulatory system
Blood pressure = cardiac output X peripheral resistance
Thus, during exercise the heart increases cardiac output and increases blood pressure. If stress causes the blood vessels to contract and increase peripheral resistance, blood pressure increases. These are just a couple of examples of how blood pressure changes temporarily.
What controls the blood pressure?
The Brain • Neural controls regulate blood pressure by
monitoring changes in specialised receptors• Baroreceptors (stretch receptors) pick up changes in
blood vessel extension• Chemoreceptors monitor the oxygen or pH of the
blood• These receptors send information to the vasomotor
18 www.goodhealth.co.nz
• Atherosclerotic lesions accumulate even more cholesterol oxides and calcium crystal deposits that further reduce the elasticity of the artery. This can increase blood pressure due to the decreased flexibility of the blood vessels.
• Fibrous plaques can cause stagnation of blood in our blood vessels that can lead to blood clots. Clots can then block the artery, resulting in a heart attack (blocked coronary artery) or stroke (blocked artery to the brain).
• As well as damaging the internal blood vessel, the red and white blood cells and platelets can also become damaged. These damaged platelets can trigger small blood clots.
• HDL is considered beneficial because it is involved in carrying cholesterol away from the arteries towards the liver where it is broken down and removed or recycled
Arteriosclerosis is a condition that progresses very slowly and is a combination of oxidative and inflammatory damage. Prevention and treatment involves antioxidant nutrients and anti-inflammatory agents.
Conditions associated with arteriosclerosis
1. High blood cholesterol & triglycerides
Signs and symptoms• Fatty deposits in the sclera (white) of the eye or
under the skin around the eye• Extremely high fat levels in the blood may cause liver
or spleen enlargement that can lead to abdominal pain
• Blood tests are the best indication• Sometimes these conditions are asymptomatic• The New Zealand guidelines for healthy cholesterol/
triglyceride levels are: - Total cholesterol less than or equal to 5.0mmol - HDL cholesterol greater than 1.0mmol - LDL cholesterol less than 2.5mmol - Triglycerides less than 2.0mmol
Causes• A diet high in saturated, oxidised or hydrogenated
fats, cholesterol containing foods and processed carbohydrates such as white flour and sugar
• Genetic factors - some people are predisposed to high LDL cholesterol, e.g. familial hypercholesteraemia, where the LDL receptors are deficient or defective (1 in 500 people)
• Elevated Lipoprotein(a), a particularly damaging lipoprotein (vitamin C deficiency may increase
Part four: The cardiovascular systemWHAT CAN gO WRONg
Cardiovascular disease (CVD) (Arteriosclerosis – hardening of the arteries)• Cardiovascular disease is one of the leading causes
of death in New Zealand• Fatty streaks, the precursors to cardiovascular
disease, develop slowly and can be seen in children’s blood vessels by the age of 10
• Atherosclerosis is the most common type of arteriosclerosis. It is a condition whereby the arteries accumulate cholesterol oxides and become thickened and narrowed.
• The vessels that supply blood to the heart (the coronary arteries) are often affected and total occlusion (blockage) can result in a heart attack
• When the carotid arteries, which supply blood to the brain, become blocked a stroke can result
The development of atherosclerosis• Cholesterol and fats are carried in the body by
specialised fat-carrying proteins called lipoproteins • There are two main classes of lipoprotein: - LDL low-density lipoprotein (commonly called ‘bad’
cholesterol) - HDL high-density lipoprotein (commonly called
‘good’ cholesterol)• LDL is the major carrier of cholesterol within our
body. It delivers cholesterol to cells that need it. In abnormal conditions cholesterol is also deposited in the smooth muscle fibres of our arteries.
• LDL’s are very susceptible to damage by oxidation (the process by which a molecule is chemically changed). Damaged cells are detected by the body’s immune system and destroyed by macrophages (White blood cells that engulf unwanted material)
• Unfortunately, not all the damaged LDL’s are destroyed and these can accumulate within our artery walls
• White blood cells called monocytes also gather and cause further oxidative damage
• This process eventually damages the inside of the arterial wall and promotes the formation of foam cells; cells that contain harmful oxidised cholesterol molecules
• These foam cells join up to form fatty streaks that produce a fibrous protein called collagen. Collagen creates a fibrous plaque which can narrow the lumen of the artery and decrease blood flow.
nervous and cardiovascular systems 19
module two
Lipoprotein(a))• Liver damage or disease• Smoking• Low thyroid function• High homocysteine levels – these cause an
increase in LDL oxidation. (Homocysteine levels may be decreased by B6, B12 and folic acid supplementation)
• Low levels of vitamin C may increase the accumulation of cholesterol in the liver
• Low levels of antioxidants, especially vitamin E• Poorly controlled diabetes• Stress
Treatment• A diet low in saturated fats and processed
carbohydrates, especially sugars• Use olive oil or avocado oil for cooking and flax oil for
dressings. Use no processed fats such as margarine or fried oils that may oxidise.
• Increase dietary fibre to help cholesterol removal via the bowel. Oat bran and rice bran are good fibre sources.
• Eat more fish and less red meat• Avoid tea, coffee and smoking• Drink 2 litres of pure water daily• Eat lots of fresh vegetables and berries such as
cherries, blueberries and raspberries for their antioxidant content (anthocyanidins)
• Reduce alcohol intake as it increases triglyceride levels and impairs liver function
• Check homocysteine and blood sugar levels regularly• Do a regular Body cleanse™ detox for optimal liver
function• Undertake regular aerobic exercise• Keep within a healthy weight range• Increase dietary intake of garlic and onions• Vegetarians have far lower rates of heart disease;
therefore diets based on more fruit, vegetables and plant-based proteins are associated with a healthier cardiovascular system

4. AnaemiaAnaemia is characterised by a reduction in red blood cell or haemoglobin levels. It is not generally considered a disease but rather a symptom of a disease process or alteration in body function.
Signs and symptoms• If the condition is slow developing the loss of red
blood cell mass can reach 50% before signs and symptoms appear
• Vegetarians, vegans, children, elderly and pregnant women are more often anaemic than other healthy people
• Fatigue or weakness• Light-headedness• Brittle hair, spoon nails• Pale skin, conjunctiva or nail beds• Heart palpitations• Headaches or abdominal pain
22 www.goodhealth.co.nz
iron absorption• Drink Nettle tea for its high iron and nutrient content• Conventional iron formulas can deplete vitamin E and
cause gastric upsets
• Dizziness or fainting• Shortness of breath• Mood changes• B12 deficiency anaemia: sore tongue, yellowing of
the skin, tingling in the extremities or nerve damage
CausesExcessive bleeding is the most common cause. • Obviously this will cause severe symptoms if the loss
is significant and sudden, as occurs as the result of an accident or ruptured blood vessel (Medical emergency)
• More commonly, blood loss is caused by chronic bleeding such as nosebleeds, haemorrhoids, intestinal ulcerations, tumours or heavy periods
• Certain medications can deplete iron e.g. aspirin, some antibiotics
• Low stomach acid (hypochlorhydria) decreases iron absorption
Decreased RBCs production due to:• Iron deficiency (microcytic anaemia)• B12 or folic acid deficiency (pernicious anaemia or
macrocytic anaemia)• Vitamin C deficiency• Intestinal malabsorption syndromes (Crohn’s disease,
sprue, coeliac)• Chronic disease or frequent infections• Insecticides damaging bone marrow
Increased RBCs destruction due to:• Enlarged spleen• Mechanical damage (rare)• Autoimmune destruction• Genetic abnormalities e.g. sickle cell anaemia,
thalassaemia
Treatment• A blood test should be done to determine iron, B12
and folate levels because a folic acid deficiency can mask a B12 deficiency
• Treat the cause if possible e.g. reduce bleeding• If iron levels are low, eat more iron-containing foods
such as red meat and green vegetables• To increase folic acid, eat lots of fresh fruit and
vegetables• B12 containing foods include milk, meat, eggs and
cheese• Take bitters (Gentian) or lemon juice before meals to
increase nutrient absorption esp. B12 and iron• Avoid drinking tea and coffee with iron-rich foods as
they interfere with iron absorption• Diet should be rich in protein, calcium, vitamins B, C
and E• Avoid smoking as the cadmium in cigarettes reduces
