Answer 2

Leukocytes (WBC) are divided into granulocytes and agranulocytes:Granulocytes (have granules)
a. Neutrophils are the most abundant WBC = 54%-62%; also called polymorphonucleocytes (PMN);
they use a process of phagocytosis (eat) foreign particles (disease organisms & debris).
b. Eosinophils 1-3% of total WBC's. They kill parasites and are responsible for allergic reactions.
increased numbers during parasitic infections (tapeworm, hookworm).
c. Basophils <1% of total WBC's. They release heparin which inhibits blood clotting and also release histamine, a vasodilator helpful in inflammatory responses (increases blood flow to damaged tissue).
They may leave bloodstream and develop into mast cells (antibodies attach and cause mast cell to burst, releasing allergy mediators).
Agranulocytes (no granules)
a. Monocytes 3-9% of total WBC's and are phagocytes and are the largest WBC, 12-20 microns.
In the blood they phagocytes but in tissues they are called macrophages. you would see increased numbers during typhoid fever, malaria, and mononucleosis.
b. Lymphocytes 25-33% of total WBC's which live for several months to years
