LESSON 1. THE main features of cardiovascular system
CLOSEDThe human cardiovascular system is closed: the blood is confined to the vessels
DOUBLEThe human cardiovascular system includes two circulatory paths
The Pulmonary circuit (small circulation)
The Systemic circuit (great circulation)

Lesson 2: The heart
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
LESSON 2. THE HEARTLocation of Heart in Thorax: between the lungs
Your heart is a pump. It's a muscular organ about the size of your fist and located slightly left of center in your chest.
Heart wall is formed by three layers
1. Pericardium: outside layer
2. Myocardium: middle layer, mostly cardiac muscle (striated and involuntary)
3. Endocardium: inner layer
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
LESSON 2. THE HEART HAS FOUR CHAMBERSThe heart is divided into the right and the left side. The division protects oxygen-rich blood from mixing with oxygen-poor blood.
Valves keep blood moving in the correct direction
Each side of the heart has
an atrium, the upper chamber, and a
ventricle, the lower chamber
·Valves open as blood is pumped through·Close to prevent backflow
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
LESSON 2. HOW DOES THE HEART WORK?A beating heart contracts and relaxes. Contraction is called systole, and relaxation is called diastole.
During systole, your ventricles contract, forcing blood into the vessels going to your lungs and body — much like ketchup being forced out of a squeeze bottle….
During diastole your ventricles relax and are filled with blood coming from the upper chambers, the left and right atria

LESSON 3. THE BLOOD CIRCULATION
First of all: the right part of the heart is syncronized with the left one, they work together in the same way, nevertheless we will simplify the circuit of blood flow considering first what happens in the right part of the heart and then in the left….GOOD WORK!
Superior vena cava
Inferior vena cava
RIGHT PART OF THE HEART (receive and pump oxigen poor blood). ATRIUM AND VENTRICLE ARE IN DIASTOLE: THEY FILL UP WITH BLOODOxigen poor blood from the upper body is channeled into superior vena cava while that from the lower body enters through the inferior vena cava. These veins empty their blood into the relaxed right atrium (diastole), tricuspid valve opens so that blood can flow from the atrium into the relaxed ventricle (diastole), Semilunar valve is closed

START Arteries deriving from aorta carry blood to arteriole, then blood enters capillaries located in the tissues Blood moves from pulmonary capillaries into venules and then veins Blood moves from pumonary ccour Left atrium contracts (systole) , pumps blood into relaxed ventricle
(diastole) Left ventricle contracts, pumps blood into aorta Oxygen moves from blood in the capillaries to cells, carbon dioxide
moves in the opposite way Poor oxygen blood from capillaries enters venules, then veins and
returns to the right part of the heart via superior and inferior vena cava
Pulmonary veins carry the oxygenated blood to the left side of the heart.

Blood is pumped by the heart into large arteries, it then flows into smaller arterioles and finally into a network of capillaries. The blood passes from capillaries into venules, then larger veins and returns to the heart
Arteries and veins have three layers (tunics)1. Tunic intima with
an epitelium called Endothelium
2. Tunic media composed by unvoluntary smooth muscle
3. Tunic externa, mostly fibrous connective tissue
LESSON 5. THE BLOOD VESSELS
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
LESSON 5. THE BLOOD VESSELS: A COMPARISON
Blood vessel Function Adaptions
Artery carry blood away from heart at high pressure
thick, elastic, muscular walls to withstand pressure and to exert force (pulse)
Capillary allow exchange of materials between blood and tissues thin permeable walls
Vein return low pressure blood to heart
Large diameter to offer least flow resistance. Valves to prevent back flow.
The structure of blood vessels is correlated with their functions:
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
LESSON 5. BLOOD FLOW IN A VEINBy the time the blood reaches the veins, its pressure has dropped to near zero. When the muscle of the body conctract, they squeeze blood to the heart. Moreover, valves along veins prevent backflow. When these valves don’t close properly, you have varicose veins.

Thin- walled capillaries allow
exchanges of gas, nutrients and waste products with tissues
Oxygen passes for diffusion through the capillary wall and into the tissues, carbon dioxide passes from the tissues into the blood
Capillaries bed= capilllaries net

LESSON 5. THE ROLE OF CAPILLARIES
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
Blood pressure: the force that is exerted by blood against blood vessel walls
Blood pressure is highest in large arteries BUT will rise and fall as heart pumps, in fact you have • highest pressure (systolic pressure) with left ventricular systole (blood is forced into
aorta)• lowest pressure with ventricular diastole (diastolic pressure)
Pressure in blood vessels decreases as the distance away from the heart increases
Measurements by health professionals are made on the pressure in large arteries

LESSON 7. WHAT’S THE RELATIONSHIP ABOUT CARDIOVASCULAR AND RESPIRATORY SISTEMS?
Gas exchange occurs between air in the alveoli and blood in the capillaries . Oxygen diffuses across the alveolar wall and enters the bloodstream, while carbon dioxide diffuses from the blood across the alveolar wall to enter the alveoli.
autore: Elena Bruno. Tirocinio, corso di perfezionamento CLIL
To understand ventilation, it is necessary to realize that the lungs adhere to the thoracic cavity by way of the pleura.
During inspiration, the thoracic cavity and, therefore, the lungs expand so that air is drawn in.
During expiration, the thoracic cavity and, therefore, the lungs resume their original positions and pressures. Now air is forced out.
