Detailed explanation-1: -Generally, macrophages ingest and degrade dead cells, debris, tumor cells, and foreign materials. They promote homeostasis by responding to internal and external changes within the body, not only as phagocytes, but also through trophic, regulatory, and repair functions.

Detailed explanation-2: -One of the most important functions performed by macrophages during the induction of an immune response may be the presentation of antigen to antibody-forming cell precursors in a molecular form appropriate for cell activation.
