Question

What is blood plasma and explain the constituents & functions of blood plasma

Answer 1

Plasma constitutes 55% of total blood volume. Composed of 90% water, salts, lipids and hormones, it is especially rich in proteins (including its main protein albumin), immunoglobulins, clotting factors and fibrinogen. ... Clotting factors, in combination with platelets, control hemorrhaging

Answer 2

☆ Blood is a special connective tissue consisting of a fluid matrix called plasma ( devoid of fibres ) and formed elements.

Plasma :

• It is straw colour (pH 7.35 - 7.45), viscous aqueous solution (viscosity is due to the presence of various protiens and other cellular materials) constitutes about 55% to total volume of blood, about 30-35% of total extracellular fluids (ECF).

Constituents of Blood Plasma :

• Water is about 90% - 92% and protiens contribute 6% -8%.

• Diffusible constituents include electrolytes, anabolic and catabolic substances, hormones and vitamins.

Non-diffusible constituents include albumins, globulins, fibrinogen and various enzymes.

• Major protiens are globulins, albumins & fibrinogen.

• It also contains organic substances like glucose, urea (small amount), amino acids, lipids, endocrine secretion, enzymes.

• Factors for cogulation are also present is the plasma in an inactive form.

• Plasma without the clotting factors is called Serum.

Functions

• Fibrinogens are needed for clotting or cogulation.

• Albumins most abundant plasma protein help in osmotic balance.

• Globulins are primarily involved in defense mechanisms.

• It carries the digested food materials food materials amd endocrine secretions to different parts of body. It maintains the actual continuity of flow.
