Neutrophil, Eosinophil, Basophil


  • A: Neutrophil, heterophil, and polymorphonuclear leukocytes have multiple lobes in the nucleus, and small granules

    B: Lymphocyte
  • A: Neutrophil also known as polymorphonuclear cells or heterophils have many lobules in the nucleus and have small granules within the cytoplasm.

    B: Red blood cells are also known histologically as erythrocyte
  • A: Neutrophil with multiple lobes

    B: Platelet or thrombocyte
  • - 40-75% of white blood cells (WBCs)

    - 1 Week in circulation and 1-4 days in tissue

    - Active in acute inflammatory response. Phagocyte.

    B: RBC


  • A: Eosinophil has large acidophilic staining granules. When compared to the neutrophil the granules in the acidophil are large
  • - 1-6% of white blood cells (WBC)

    - 2 week life span in circulation

    - Responsible in parasitic invasion


  • A: Basophil has large basic staining granules that are purple and obscure the nucleus and the cytoplasm.
  • - less than 1% of WBCs

    - 1-2 year lifespan in circulation

    - Active in allergic reactions

    - Secrete histamine and heparin
