What are leucocytes? Mention their different kinds.

Answer»

Leucocytes are known as white blood cells (WBC). They are oval/rounded or irregular in shape. WBCs have nuclei but are devoid of haemoglobin. 

They are of two kinds: 

(1) granulocytes, and (2) agranulocytes. 

Granulocytes possess granules of varying sizes and have lobed nuclei. 

They are of three kinds: 

(1) basophils, (2) acidophils, (3) neutrophils 

based on the staining feature. Monocytes and lymphocytes are two types of agranulocytes. They are non-granular and always have only one nuclei in individual cell.
