4. The system that moves
blood throughout the body.
This system transports
oxygenated blood from
lungs and heart throughout
the body via theblood
vessels.
VEIN
HEART

9. Blood is a fluid which
travels through circulatory
system suspended in a
yellowish fluid called
plasma.

PLATLETS
WHITE BLOOD

10. What does
blood do in
our body?

11. • Blood is the vehicle for metabolic communication between
the organs of the body.
• Blood transport nutrients from small intestine to the liver
and others organs.
• Blood transport waste product to the kidney for excretion.
• Blood transport oxygen from lungs to the tissue and carbon
dioxide generated during the respiratory metabolism to
lungs for excretion.

12. Do we all
have same
type of
blood?

13. No, We all
have different
blood group.

14. WHAT ARE BLOOD TYPES?
There are four main blood types: A, B, O, and AB.
Each blood type is slightly different and has
different antibodies and antigens. It's important
that blood donors have matched blood types or a
person can get very sick.

15. Today I will
find my blood
group from
Doctor Uncle

16. Do you know? O
blood group is
universal donor &
AB is universal
recipient.

19. Red blood cell Contain red
pigment called haemoglobin.
Haemoglobin Bind with oxygen
and transport it to other part of
body.
The presence of haemoglobin
makes blood look red.

20. I am
Erythrocytes

21. The red colour of
RBC is due to
presence of
hemoglobin

22. White blood cell fight against germs that may enter body.

23. White blood cell fight against germs that may enter body.
We also call
it Leukocytes

24. WBC are
called
‘soldier’ of
body

26. Your blood contain many tiny
cells called platelets. They form
your blood clot , which means
that if you get a cut, some of
your platelets stick together to
plug the hole in the blood vessels
wall caused by cut to form a
scab to protect the healing skin
underneath.

27. Your body has an astonishing network of living tubes
called blood vessels that transport vital supplies.
Altogether about 100,000km of blood vessels fits into
your body and keep your body cells working.
You have three types of blood vessels:-
Arteries
Veins
capillaries

35. Carry blood away from the heart
Thick muscular walls
Lots of elastic tissue in wall
Relatively small lumen
Blood under high pressure
Blood flow rapid
Blood flows in pulses
No valves
The largest artery in the body is AORTA

37. ARTERY outer layer

40. ARTERY outer layer

fibrous tissue
inner lining
(endothelium)

41. Link up arteries and veins in the tissues
No muscle
Wall made up of one cell thick
endothelium
Small lumen – just large enough for a red
blood cell to squeeze through
Pressure falls as blood passes along
capillary
Blood flowing is slowing down
No pulse
No valves
CAPILLARIES

43. Carry blood back to the heart
Thin muscular walls
Little elastic tissue in the wall
Relatively large lumen
Blood under low pressure
Blood flow is slow
No pulse
Valves prevent backflow of
blood

50. ARTERY VEIN CAPILLARY
Thick-walled with narrow
lumen
Thin walled with wide lumen Thin –walled narrow tubes
with narrow lumen
Blood flows from heart to other
body parts.
Blood flows from body organs
to the heart.
Capillaries join artery with the
vein & form a network in the
body organs.
Supplies blood to body Collects blood from body
organs & bring it back to
heart.
Helps in the exchange of food,
oxygen& carbon dioxide
between blood & tissue.
Carries oxygenated
blood(except pulmonary
arteries).
Carries deoxygenated blood
(except pulmonary veins).
Carries both type of Blood.

53. How does our body transport food,
Oxygen, carbon dioxide and waste?
Answer: through a fluid called

54. Blood travels through our bodies
Through BLOOD VESSELS
What are the 3 types of BLOOD VESSELS?
VEINS
ARTERIES
& CAPILLARIES

55. What is the name of the LARGEST
ARTERY?
Hint: It is located within the HEART.
