Leukocytes are dumb

Difference Between Granulocytes and Agranulocytes

Granulocytes have granules in the cytoplasm

Agranulocytes do not have granules in the cytoplasm

Neutrophils

-Most numerous white blood cells (50-70%)

-Multi lobed nucleus

-Attracted to sites of inflammation

-Use phagocytes to engulf bacteria

Eosinophils

-2-4% of white blood cells

-Two-lobed nucleus

-Use enzymes to digest parasitic worms

Basophils

-Rarest white blood cells (less than 1%)

-Release histamine: an inflammatory chemical that attracts other white blood cells to the site of infection

Lymphocytes

-25% of white blood cells

-Second most numerous white blood cell

-Have a large nucleus that takes up most of the cell

-Found in the lymphnodes

-Two types: T-Cells and B-Cells

Monocytes

-3-8% of white blood cells

-Largest leukocytes

-Have a u-shaped nucleus

-Become macrophages: phagocytes that engulf viruses and other pathogens
