What are the substances present in the plasma?

Fibrinogens are needed for clotting or coagulation of blood. Globulins primarily are involved in defense mechanisms of the body and the albumins help in osmotic balance. Plasma also contains small amounts of minerals like Na⁺, Ca++, Mg++, HCO3 –, Cl–, etc. Glucose, amino acids, lipids, etc., are also present in the plasma as they are always in transit in the body. Factors

for coagulation or clotting of blood are also present in the plasma in an inactive form. Plasma without the clotting factors is called serum.
