Question

What is the relationship between blood and plasma

Answer 1

Blood is a fluid tissue which consists of two components namely the Liquid components and the Cellular components. The liquid components consists of plasma and the cellular components consists of the blood cells- the Erythrocytes [ RBC ], Leucocytes [ WBC ] and Thrombocytes [ platelets ]. Hence plasma comprises 45% of the total blood.

The Plasma is made up of water and other organic and inorganic substances. Water comprises of 90% of total plasma and the organic and other substances are only 10% in total plasma.

There are four main proteins which are present in the plasma. They are Serum Albumin, Serum Globulin. Prothrombin and Fibrinogen. The Serum albumin and globulin are used for various metabolic activities. The Prothrombin and the Fibrinogen are mainly used in clotting mechanism of the blood. The thrombin and fibrinogen are important proteins which are very essential for the blood clotting.
