Question

Discuss briefly the blood in the body and the cellular content present in the blood?

Answer 1

Blood in the body is a heterogeneous connective tissue in the form of a fluid that is in a non stop circulation performing many important biofunctions along the way. With the cardiovascular system, it forms an efficient transport system in the body. 

Composition:

Blood can be divided into two parts in terms of composition: Cell mass (45%) and Plasma (55%).

Cellular content:

These are the formed elements in the blood. Cellular content includes erythrocyes, leucocytes, thrombocytes (tiny fragments of bone marrow cells) and occassional plasma cells. 

Leucocytes or White Blood Cells (WBCs) have two subcategories: 

1. Granulocytes

2. Agranulocytes

On the basis of staining granulocytes are further diveded into: Neutrophils, Eosinophils and Basophils. 

Agranulocytes are divided into Lymphocytes and Monocytes.

Centrifugation at 3K rpm for 30 minutes brings seperation of the cells from the plasma.
