Study Notes
Granulocytes
-
Neutrophils:
- Most common white blood cell (50-70%)
- Multi-lobed nucleus
- Attracted to sites of inflammation
- Use phagocytosis to engulf bacteria
-
Eosinophils:
- 2-4% of white blood cells
- Two-lobed nucleus
- Use enzymes to digest parasitic worms (e.g., tapeworms, flukes)
-
Basophils:
- Rarest white blood cells (less than 1%)
- Release histamine, an inflammatory chemical that attracts other white blood cells to the site of infection
Agranulocytes
-
Lymphocytes:
- 25% of white blood cells
- Most numerous white blood cell
- Large nucleus that takes up most of the cell
- Found in lymph nodes
- Two types: T cells and B cells
-
Monocytes:
- 3-8% of white blood cells
- Largest leukocytes
- U-shaped nucleus
- Become macrophages—phagocytes that engulf viruses and other pathogens
