Granulocytes
Granulocytes are white blood cells whose
cytoplasm contains tiny granules. The cells are named according to
the staining characteristics of the granules.
![bullet](_themes/anatomy2/capbul1a.gif) | Neutrophils -
the granules do not stain with normal blood stains so we generally
see just the multilobed nucleus. Neutrophils are phagocytic cells;
they engulf foreign material.

![bullet](_themes/anatomy2/capbul1a.gif) | Eosinophils have
red-staining granules. They seem to be attracted to allergic
reactions in the body.
|
![bullet](_themes/anatomy2/capbul1a.gif) | Basophils have
dark blue-staining granules. They are the least numerous blood
cells. They help initiate the inflammatory process at sites of
injury.
