Agranulocyte White Blood Cells (WBCs).

Monocyte(Large WBC):- Size 10-18 μm.

Nucleus:- 

I). Pale Eccentric 

II). Single, round 

III). Ecentric in position

IV). Nuclear chromatin

Cytoplasm:- Pale Blue Clear

Functions:-

I). Active Phagocytosis

II). Second line of defence

III). Monocyte may also kill tumor cells.

Monocytosis:- Increase in the number of monocytes.

Causes:-

I).   Tuberculosis

II).  Syphilis

III). Some Leukemia

Monocytopenia:- Decrease in the number of monocytes.

Causes:- Hypoplastic Bone marrow.
