Today's Medical Topic: Histology of Blood Part Deux.
The Tissue Sample: Agranulocytes. If you guessed that agranulocytes have no granules in them then you are a genius, sir and/or madam, and you have no business reading this blog.
Agranulocytes all arise from ancestral stem cells, however, unlike granulocytes, agranulocytes do not all come from a myeloid stem cell. A monocyte arises from a myeloid stem cell and lymphocytes arise from a lymphoid stem cell. Lets take a look.
Next up...something. Something else about blood.

This is a monocyte
- Has a kidney-shaped nucleus with an "invagination" which is what the red arrow is pointing to.
- Is more than three times larger than a red blood cell.
- Monocytes are the bad boys of the cell world they develop into macrophages and eat stuff.
- Macrophages can engulf and break down almost anything they can fit inside them.

This is a lymphocyte
- Has a spherical nucleus.
- Is about the same size as a red blood cell
- Comes in several flavors but lymphocytes mount immune response by direct cell attack or by synthesizing antibodies.
