2. What does blood consists of?
-Blood consists of…
Red blood cell
Plasma
White blood cell Platelets

3. What are the functions of Blood?
-Transport oxygen away from the lungs and around the body
-Transport nutrients such as glucose from
the digestive system into the cells in our
Bodies.

4. Red blood cell
What are the functions of the red blood cell?
-The primary function of red blood cells is to carry oxygen
from the lungs to the tissues around your body. They are also
important in getting waste carbon dioxide from your tissues
to your lungs, where it can be released.

5. White blood cell
What are the functions of the white blood cell?
-The white blood cell are part of the immune system. The body
uses white blood cells to fight infection and foreign objects in
the body .Several types of white blood cells used to fight
different infections.

6. Plasma
What are the functions of the plasma?
-Plasma is the liquid part of blood and carries dissolved substances such as glucose
and other products of digestion, hormones, vitamins, urea and carbon dioxide and
transports them to all parts of body .The plasma makes the blood liquid, the cells in
the blood are suspended in the plasma. Thus ,when you cut yourself ,the blood
comes out as a liquid.

7. Platelets
What are the functions of platelets?
-Platelets are certain types of cell present uniformly in the bloodstream.
Platelets are responsible for the healing of injuries and the provision of fibrin(wide
elastic protein formed from fibrinogen when blood clots)threads to seal the wounds.
Platelets are red in colour and oval in shape.

9. BLOOD VESSELS

10. What are the blood vessels and their uses?
-Blood vessels are part of the circulatory system that transport
blood throughout the body.
There are 3 major types of blood vessels: Arteries, veins and
lastly the capillaries.

11. ARTERIES
What are the functions of arteries?
-The arteries carry blood away from the heart. This blood is
oxygenated, exceptions made for the pulmonary and
umbilical(supply deoxygenated blood from the fetus) arteries.
The circulatory system is important for the delivery of oxygen
and nutrients to all cells and the removal of carbon dioxide and
waste products, maintenance of optimum pH and the mobility of
the elements.

12. CAPILLARIES
What are the functions of capillaries?
-Capillaries are the smallest of a body's blood vessels. Their endothelial linings are
only one cell thick. They enable the exchange of water , oxygen ,carbon dioxide
and many other nutrients and waste chemical substances between blood and
surrounding tissues .New capillaries are formed by the process of blood vessels
formation occurring by a production of endothelial(thin layer of cells that lines the
interior surface of blood vessels)cells forming into vascular tubes.

13. AND FINALLY….

14. VEINS
What are the functions of the veins?
-In the circulatory system, veins are blood vessels that carry
blood back towards the heart. Veins are often closer to the skin and
contain valves(a device to control the flow of liquid) to help keep
blood flowing toward the heart.
