Arteries take blood away from the heart. The walls of an artery are made up of thick muscular walls and elastic fibres. Veins carry blood towards the heart and also have valves. The capillaries link arteries and veins, and have a one cell thick wall. Blood is made up of four main things plasma, the liquid part of the blood; Red Blood Cells to carry oxygen; White Blood cells to protect the body from disease and platelets to help blood clot.

4. What is the meaning of circulatory system?
 Transportation device in human body is a system
called blood circulatory system, Human blood
circulatory system consist of blood, blood circulatory
organs, and lymph circulation, while blood circulatory
organs consist of heart and blood vessel that contain
blood

6. WHAT IS THE FUNCTION BLOOD ?
Blood is transporting organ in human , that is
transporting food essence and oxygen than is
circulated to the entire part of body cells.
Blood is body liquid that is found inside the
hard and blood vessels. Blood has red color
because it contains hemmoglobine (Hb), the
volume of body’s blood is about 8% of his body
weight.

14. How does the Heart work?
STEP ONE
blood from the blood from
body the lungs
The heart beat begins when the
heart muscles relax and blood
flows into the atria.

15. How does the Heart work?
STEP TWO
The atria then contract and
the valves open to allow blood
into the ventricles.

16. How does the Heart work?
STEP THREE
The valves close to stop blood
flowing backwards.
The ventricles contract forcing
the blood to leave the heart.
At the same time, the atria are
relaxing and once again filling with
blood.
The cycle then repeats itself.

17. blood from the heart gets around
the body through blood vessels
There are 3 types of blood vessels
a. ARTERY
b. VEIN
c. CAPILLARY

18. The ARTERY
Arteries carry blood away from the heart.
the elastic fibres allow
the artery to stretch
under pressure
thick muscle and
the thick muscle can
elastic fibres
contract to push the
blood along.

19. The VEIN
Veins carry blood towards from the heart.
veins have valves
which act to stop the
blood from going in
the wrong direction.
thin muscle and
elastic fibres body muscles surround the veins
so that when they contract to
move the body, they also squeeze
the veins and push the blood along
the vessel.

20. The CAPILLARY
Capillaries link Arteries with Veins
they exchange materials
between the blood and
other body cells.
the wall of a capillary
is only one cell thick The exchange of materials
between the blood and the
body can only occur through
capillaries.

21. The CAPILLARY
A collection of capillaries is known as a capillary bed.

capillaries

22. what’s in
digested food
red blood cells white blood cells
oxygen waste (urea)
carbon dioxide platelets
plasma hormones

23. The Blood
red blood cell white blood cell
platelets plasma

24. Red Blood Cells
contain haemoglobin, a
a biconcave disc that is molecule specially designed
round and flat without a to hold oxygen and carry it
nucleus to cells that need it.
can change shape to an
amazing extent, without
breaking, as it squeezes
single file through the
capillaries.

25. White Blood Cells
there are many different types and
all contain a big nucleus.
the two main ones are the
lymphocytes and the macrophages.
macrophages ‘eat’ and digest micro-
organisms .
some lymphocytes fight disease by making antibodies to destroy
invaders by dissolving them.
other lymphocytes make antitoxins to break down poisons.

26. Platelets
Platelets are bits of cell
broken off larger cells.
Platelets produce
tiny fibrinogen
fibres to form a net.
This net traps other
blood cells to form a
blood clot.

27. Plasma
It also contains useful
things like;
• carbon dioxide
A straw- • glucose
coloured
liquid that • amino acids
carries the • proteins
cells and the
platelets • minerals
which help • vitamins
blood clot.
• hormones
• waste materials
like urea.
