• Neutrophils (न्यूट्रोफ़िल) — 60–65% of WBCs; phagocytic — destroy foreign organisms.
• Eosinophils (इओसिनोफ़िल) — 2–3%; resist infections; allergic reactions.
• Basophils (बेसोफ़िल) — 0.5–1% (least); secrete histamine, serotonin, heparin; inflammatory reactions.
• Lymphocytes (लिंफ़ोसाइट) — 20–25%; B and T forms — immune responses.
• Monocytes (मोनोसाइट) — 6–8%; phagocytic.
