Monocytes
lymphocytes

-granulocytes have spotted cytoplasm as a result of membrane bound organelles

-phagocytize bacteria
-release antimicrobial chemicals
-increases in bacterial infections
-60-70% of wbc

-phagocytize antigen-antibody complexes, allergens, and inflammatory chemicals
-release enzymes that weaken or destroy parasites
-increases in parasite infections, allergies, disease of spleen and cns
-increases seasonally and day and night phases
-2-4%

Secrete histamine (vasodilator) which increases blood flow to a tissue
-secrete heparin (anticoagulant) which promotes mobility of other wbc's
-increases in chicken pox, sinusitis, diabetes mellitus, polycythemia
-.5-1%

Destroy cancer cells, cells infected with viruses, and foreign cells
-present antigens to activate other cells of immune system
-coordinate other immunce cells
-secrete antibodies
-serve in immune memory
25-33%

-differentiate into macrophages (phagocytic cells of tissues
-phagocytize pathogens, dead neutrophils nad debris of dead cells
-present antigens to active other immune cells
-increase in viral infections and inflammation
3-8%

Hematocrit
-differential white blood cell count

To count the number of each white blood cell in a sample of blood.
-with the information found it can be an indicator as to any infection or disease
