What four nutrients are found in plasma?

Blood plasma is the non-cellular component of the blood. It is a watery matrix of ions and proteins and makes up 50-60% of the total blood volume.

The functions of blood plasma along with its content substances are as follows:

1. SERUM ALBUMIN-->(7-9%)

--------------------------------------…

a. osmotic balance

b. pH buffering

c. Ca2+ transport

2. FIBRINOGEN and PROTHROMBIN

--------------------------------------…

a. takes part in blood clotting

3. IMMUNOGLOBULINS

--------------------------------------…

a. Antibodies involved in the immune response

4.alfa-globulins

--------------------------------------…

a. bind and transport hormones, lipids, fat soluble vitamins

5. beta-globulins

--------------------------------------

a. bind and transport iron, cholesterol and fat soluble vitamins

6. ENZYMES

--------------------------------

a. Take part in and regulate metabolic activities

7. MINERAL IONS IN PLASMA

--------------------------------------…

Na+, bicarbonate, Magnesium, potasium, calcium and others have these fuctions:

a. osmotic balance

b. pH buffering

c. regulation of membrane permeability

d. and other body function,e.g. Ca+ takes part in blood clotting process.

8. WATER (The main/major constituent)

--------------------------------------…

A vital factor for many crucial functions....such as;

a. thermoregulation

b. regulating blood pressure and volume

c. distributing heat

d. transporting dissolved substances

f. provides body cell with water

And that's, I hope enough than you might have wished.
