Anatomy & Physiology Question #16


Which structures participate in phagocytosis?


  1. Cytoplasm: Red blood cells
    • Rationale:
  2. Immune system: White blood cells
    • Rationale:
  3. Cytoplasm; stem cell
    • Rationale:
  4. Immune system; Platelets
    • Rationale:



The correct answer is B. The process of phagocytosis occurs when the cell is trying to destroy an invading cell, like a virus. These are used by the immune system cells as a defense mechanism. The other cells such as red blood cells, stem cells, and platelets are not involved in the immune system and do not represent phagocytosis.
