Cells – the basic unit of life
Tissues – clusters of cells performing a similar function
Organs – made of tissues that perform one specific
function
Organ Systems – groups of organs that perform a
specific purpose in the human body
consisting of many billions of cells as well as components
outside of the cells.
Human Body Contains 11 organ systems…

1. NERVOUS SYSTEM
A. Central Nervous System :
a. Brain,

3. CIRCULATORY SYSTEM
Artery :
Blood vessel that carries blood
away from the heart and toward
other tissues and organs.
Arteries deliver oxygen and
nutrients to every cell of the
body.
Vein:
Blood vessels those carry
blood that is low in oxygen
content (Deoxygenated blood)
from the body back to the
heart.

5. MUSCULAR SYSTEM
A. Visceral Muscle:
found inside of organs like
Stomach,
Intestines &
Blood vessels.
B. Cardiac Muscle:
found in the Heart.
C. Skeletal Muscle:
are attached to bones
through tendons.

6. SKELETAL SYSTEM
The adult
human
skeletal
system
consists of
206 Bones,
as well as a
network of
Tendons,
Ligaments &
Cartilage.

7. ENDOCRINE SYSTEM
Collection of glands that produce hormones that regulate:
• Metabolism,
• Growth & Development,
• Tissue function,
• Sexual function,
• Reproduction,
• Sleep,
• Mood, etc.

8. EXCRETORY SYSTEM
Responsible for the elimination of wastes

9. REPRODUCTIVE SYSTEM
New life begins when an egg from a woman is fertilised by sperm from a man.

10. DIGESTIVE SYSTEM
A group of organs working together to convert food into basic
nutrients, which the body uses for energy, growth and cell repair.

11. IMMUNE SYSTEM
Balanced state of having adequate biological defences to fight
infection, disease, while having adequate tolerance to avoid allergy
and diseases.
Immunity
White Blood Cells
• made in the bone marrow.
• move through blood and tissue.
• Every time a microbe (germ) is overcome, the immune system
remembers that microbe.
• The immune system also produces proteins called antibodies
that can help neutralise infection or the toxins.

11. IMMUNE SYSTEM
A. Active Immunity:
a. Natural active immunity -- acquired due to infection
b. Artificial active immunity – vaccination
B. Passive Immunity:
a. Natural passive immunity-- A mother’s antibodies pass across
the placenta to the foetus and remain for several months.
b. Artificial passive immunity – Used when a very rapid immune
response is needed e.g. after infection with tetanus.
Fever:
A rise in body temperature, or fever, can
happen with some infections. This is actually an
immune system response.
A rise in temperature can kill some microbes.
