Question

Quizplus · Accepted Answer

Macrophages are scavenger cells that phagocytose (engulf and digest) dead and fragmented bacterial cells in the body. They play an important role in clearing out cell debris after an infection. Lymphocytes are involved in the adaptive immune response, not in the direct removal of cell debris. Mast cells release histamine and other chemical mediators, but are not directly involved in phagocytosis of cell debris. Cytokines are signaling molecules involved in immune responses, but they are not directly involved in the removal of cell debris.
