Macrophages promote homeostasis by responding to internal and external changes within the body.
Macrophages are present in all vertebrate tissues from mid-gestation throughout life and constitute a widely dispersed organ system.
Macrophages act as phagocytes in defence against microbes and in clearance of dead and senescent cells.
Macrophages also have trophic, regulatory, and repair functions.
