Monocyte

Nucleus is lacy. Cytoplasmic fingers. Deformed by red cells.

Granules signify a lymphocyte beginning to be reactive

What are the big cell?

What are the small basophilic chunks?
Monocyte

The nucleus of this monocyte is slighly indented but is also off to one side of the cell which is another typical characteristic of a monocyte.
Monocyte

Vacuoles!

Note the strongly indented nucleus that is characteristic of some monocytes - this nucleus has a "kidney bean" shape.
Neutrophil

Mature Neutrophil: nucleus: 4-5 lobes; cytoplasm: "neutral" stained granules; size: larger than RBC.
Lymphocyte

Note the small size of this lymphocyte - very little cytoplasm is visible.
Neutrophil
Eosinophil

Eosinophil: nucleus: bilobed; cytoplasm: filled with small eosinophilic or deep red staining granules that often consume the cytoplasm; size: much larger than RBC.
Lymphocyte

Note that this lymphocyte is quite large in comparison to others (has larger volume of cytoplasm).
Lymphocyte

This lympocyte has a small volume of cytoplasm that is visible.
Basophil

Basophil: nucleus: bilobed; cytoplasm: large granules that stain "basophilic" or blue/purple-note that the granules do not completely consume the cytoplasm; size: much larger than RBC

This appears to be the only basophil in this slide; however, you should look for basophils on your other peripheral blood smear slides.
Platelets

Platelets are often found grouped together in a clump such as shown here. They
Band

This neutrophil did not reach full maturation before being released into the bloodstream. This is a common occurrence, however, a large number of these immature neutrophils often indicate an active infection.
