Ques-3 What is the function of Plasma protein? Ans: Plasma is present in the blood and constitutes the liquid part of the blood. It is made up of 90% water which is required for hydration of body tissues. 7% of plasma is composed of proteins and looks like a pale yellow liquid.Blood plasma is made up of approximately 20% of extracellular body fluid and the composition is almost similar to interstitial fluid. The major difference between the two fluids is the presence of protein content. Interstial fluid comprise of only 2% of protein because the plasma protein molecules are way too large and hence cannot penetrate through the capillary walls located in the interstitial area. And when protein does leak in small volume, the lymph takes it up and returns it back to the blood. functions of plasma protein The functions of plasma proteins include: • Osmotic or intravascular effect of plasma protein maintains fluid as well as electrolyte balance • Viscosity of plasma is maintained by the plasma protein • These are the protein reserves of our body • Performs the important function of clotting • Responds with inflammation in case of wound or injury • The gamma globulins act as antibodies and protect our body from infection • Plasma protein also maintains acid base balance
