Plasma is the colourless fluid of blood which constitutes about 55% of the blood. It helps in the transport of food, C02, waste products, and salts etc. About 6.8% of the plasma is constituted by proteins such as fibrinogens, globulins, and albumins. Fibrinogen is a plasma glycoprotein synthesised by the liver. It plays a role in the clotting of blood. Globulin is a major protein of the plasma and it protects the body against infecting agents. Albumin is a major protein of the plasma that maintains the fluid volume within the vascular space.
