PHAGOCYTOSIS

• WHAT IS A PHAGOCYTE?

  macrophage in blood and tissues
• PROCESS OF PHAGOCYTOSIS?

  1. Phagocytes in blood/ tissues
  2. Any chemicals/ debris released by pathogens/ abnormal cells attract pathogens
  3. Receptors on phagocyte surface attach to chemicals/ antigens
  4. Phagocyte changes shape to engulf pathogen
  5. Phagosome vesicle formed
  6. Lysosome fuses with phagosome = phagolysosome
  7. Releases hydrolytic/ lysozyme enzyme which hydrolyses pathogen
  8. Destroys pathogen
  9. Soluble products absorbed and used by phagocyte
