What does Macrophage act as?

Answer 1

Macrophages act as phagocytes (engulfing antigens) and digest them for specific defense of immune system to detect. They are non-specific, therefore, they just digest and excrete antigens.

Answer 2

Macrophages are a type of white blood cell that plays a crucial role in the immune system. They engulf and digest pathogens (such as bacteria and viruses), dead cells, and other harmful substances to help protect the body against infections and maintain tissue homeostasis. Macrophages also produce signaling molecules to regulate immune responses and promote tissue repair.
