      • Cellular defense; phagocytosis of small pathogens
    • Eosinophils
      • Two-lobed; Orange-Red Granulocyte
      • 2-4%
      • Vellular defense; Eats Protozoa & Parasitic Worms; Antiinflammatory for Allergic reactions
    • Basophils
      • Two-lobed; Purple Granulocytes
      • 0.5-1%
      • Anticoagulant: Heperin; Inflammatory response: Histamine
    • Lymphocytes
      • Smallest WBC; Scant cytoplasm
      • 20-25%
      • Humoral (fluid) defense; Immune System response & regulation; Antibodies; T- attack infected or cancerous cells; B- produce antibodies.
