2. FUNCTION OF BLOOD

3. AS A TRANSPORTER
Transport of gases-blood transport oxygen from lungs
to the cell and carbon dioxide from cell to lungs
Transport of nutrition –digested food and fluid are
observed in blood through the gastrointestinal tract.
blood thus supplies nutrition billions of body cells and
also transport nutrition from the store to tissues.

4. AS A VEHICLE
Follows are carries by blood to their respective places
Hormones
Vitamins
Minerals
Pigments
Enzymes

5. WATER BALANCE
Water balance of the body is maintained such that the
amount gained is counter balanced by the amount
lost.
Adjustment is made by increase or decrease in the
quantity of water lost as urine. Water is also excreted
by the skin during perspiration.

6. ACID BASE EQUITY
Blood pH is always on the alkaline side. Blood excretes
its product through the lungs, kidneys and skin to
restore the normal pH .
Blood has many buffers like haemoglobinand plasma
protein which help to prevent any shift in pH of blood.

7. IONIC EQUILIBRIUM
Ions ( i.e.-electrically charged particles ) potantially
affect various biochemical activities of the body.
Intracellular and extracellular concentrations maintain
an optimum ionic balance called homeostasis.

8. TEMEPRATURE REGULATION
Water of the blood serves as an important agent fir
tempratureregulation of the body.
Water has 1. –High specific heat
2.-High conductivity
3.-High latent heat of
evaporation
The body and through expiration of hot breath water
vapouris lost.

9. EXCRETION
Cell metabolism gives out its waste . Such waste is
collected and transport via blood to extrectoryorgan

10. BODY DEFENCE
Blood protects the body against the infection in two
ways
1-By the phagocyticof the leucocytes (WBC)
2-By the antibodies in the plasma of the blood

11. PREVENTION OF HAEMORRHAGE
Clotting mechanism of proctectsus againest
haemorrhages. These is achieved through the
formation of fibrin by thrombin in the presence of
ionic Ca and lipid accelerator factor.
Imfactclotting of blood is greater protector of blood
and therefore of life.

12. REGULATION OF BLOOD VOLUME
Plasma proteins present in blood have important
functions and one that is very vital is the maintenance
blood volume by osmosis
Hydrostatic pressure and osmotic pressure of the
blood , work in opposite direction and help to
maintain the contancyof blood volume.

13. BP. REGULATION
Various factor control blood pressure and try to keep
in normal.
Blood volume and viscosity of blood help to normalise
the blood pressure.

14. COMPOSITION OF BLOOD
Blood is a complex fluid with suspended cells
Cells constitute about 45% and the fluid called plasma
constitute 55% of blood.

15. 1 -CELLS
1.-a.-Red blood corpuscles /cell or Erythrocytes
b-white blood cells (WBC) or leucocytes
C-platelets or thrombocytes(tc)
2.-Plasma –A.-Water :90-92%
B.-Solids : 8-10%

16. PLASMA
It is a pale cream colored fluid consisting of organic
and inorganic substance in addition tiformed
elements
RBC
WBC
PLATELETS

17. A.-ORGANIC SUBSTANCE
1. Protein
2.NPN non protein nitrogenous substance
3. Carbohydrates : glucose and other sugars
4. Fats
5. various substance
Hormones
Antibodies
Enzymes

18. B-INGORNIC SUBSTANCE
Inorganic substance are
Salts
Sodium
Potassium
Calcium
Phosphorus
Magnesium
