I will also describe its functions of blood
Composition

- 45% of R.B.Cs
- 1% of W.B.Cs & platelets
Composition Of Plasma
- in Water 92% -> also Plasma proteins 7% -> and Other solutes 1%
Composition Of Plasma Protein
Albumins 60%
4.5g%
Globulins 35%
2.5% g
Fibrinogen 4%
0.3g%
Function of Albuminous
- Maintain pressure in the blood vessels
- Transports substances like fatty acid, the acids
- Hormones Steroid Hormones
Function of Glalbutins
- Its vital role in Immune system
- Its transports ions and Hormones
Function of Fibrinogens
- Essential for blood clot/ clotting factors
Causes of Plasma color

8 Functions of blood
Blood transports Q2 from lungs to tissues and CQ2
from tissues to lungs
- Its Transport Pressure
- absorbed from GIT
- Mobilized from storage depots to tissues
- It transports excretory products from tissues to
- organs of excretion like kidneys, lungs, intense and
- Skin, etc
- IT carries hormones, enzymes, antibodies, vitamins,
- inorganic and organic salts to there place of
- activity
- IT contains clotting factors [ fibrinogen ] so prevents
Homologous by coagulation
- IT also regulates
- Water balance
- Blood Ph
- Ian balance
- body Temperature
- blood pressure
- blood viscosity
- Osmotic Pressure
