Peripheral Blood Smear, 250x
- This slide shows four of the five different types of white blood
cells found in the peripheral blood. The types of white blood cells
are considered in two categories:
- Granulocytes - This group includes the neutrophils, eosinophils,
and basophils. These cells are distinguished by the presence of
azurophilic granules, thought to be lysosomes, and specific granules.
Specific granules stain with neutral or acid dye components and contain
various enzymes. The specific granules allow the three cell types to be
- Agranulocytes - These are the monocytes and lymphocytes.
They contain azurophilic, but not specific, granules.
