Question

What are the cellular components of blood?

Solution

Blood is a fluid connective tissue. It is composed of plasma (fluid) and blood cells (corpuscles).

Cellular components of blood (blood corpuscles) constitute about 45% of blood volume.

Three types of blood cells are:

(i) Erythrocytes or red blood cells: They are most abundant blood cells. Normal RBC count is 5-5.5 million/mm3 in males and 4.5-5 million/mm3 in females) RBCs help in transport of gases and maintain blood pH.

(ii) Leucocytes or white blood cells: The normal WBC count is 5000-6000/mm3 of blood. They are involved in immune response of body and act as soldiers and scavangers.

(iii) Thrombocytes or blood platelets: There are about 2,50,000 platelets/mm3 of blood. They are involved in blood clotting.
