Which blood corpuscle is largest in diameter?
Erythrocytes
Monocytes
Neutrophils
Lymphocytes
Types of Leukocytes -
A comparison of types of leukocytes is given below:
Neutrophils |
Eosinophils |
Basophils |
Lymphocytes |
Monocytes |
constitute about 60% of WBCs in blood, most abundant WBCs. |
2.3% of WBCs are eosinophils. |
constitute about 0.4% of WBCs |
constitute about 30% of WBCs |
constitute about 5.3% of WBCs |
Two to five nuclear lobes are found. |
The nucleus of eosinophils is bilobed. |
Nucleus is three-lobed |
Possess spherical nucleus with scanty peripheral cytoplasm |
A large, single nucleus is found, mostly, kidney-shaped |
The cytoplasm contains specific granules, which can take up both acidic and basic stains. |
coarse granules that take up acidic stains. |
Granules are fewer and irregular in size and shape. These granules are coarse and they take up basic stains. |
Granules are absent in the cytoplasm |
Granules are absent from the cytoplasm |
The microscopic policemen of blood |
increase in number during allergic reactions and helminthic infections can engulf antigen-antibody complexes. |
These can release histamine, heparin etc. |
Lymphocytes play an important role in immune reactions. |
They can engulf bacteria and cellular debris. |
