RED BLOOD CELLS AND NEUTROPHILS

Red blood cells are seen as biconcave disks.  Why is this shape important for their function?

Shown in the following photo are red blood cells in a smear,  small platelets (p) and a neutrophil with a multilobed nucleus.   The drumstick like projection from the nucleus is called a "Barr Body" and represents the condensed X chromosome.  This signifies that the blood was taken from a female

MONOCYTES

Monocytes are phagocytic and may have vacuoles in the cytoplasm.  They also have a horseshoe shaped nucleus or, in immature monocytes, they may have an indented nucleus.

LYMPHOCYTES

Lymphocytes are only slightly larger than red blood cells (small lymphocytes) and they have a relatively large nucleus:cytoplasm ratio.  Note that the lymphocyte in the above photo has only a thin rim of light purple cytoplasm around the dense nucleus.
