In animals, phagocytosis is performed by specialized cells called phagocytes, which serve to remove foreign bodies and thus fight infection. In vertebrates, these include larger macrophages and smaller granulocytes, types of blood cells.

involves chemotaxis, where phagocytic cells are attracted to microorganisms by means of chemotactic chemicals like microbial products, complements, damaged cells and white blood cell fragments; chemotaxis is followed by adhesion, where the phagocyte ...

Using phagocytic cells, like macrophages and neutrophils, to gain entry into the internal environment is a risky strategy because phagocytes are poised to destroy engulfed bacteria.

An important part of the mononuclear phagocyte system, make up of lymphoid tissue. It stores excess red blood cells, destroys old cells, and is capable of acting as a reservoir holding 20-30% of all blood cells.

Clumping makes the job of phagocytes easier, as they will more readily engulf bacteria in clumps. Bound antibodies sometimes serve as tags, called opsonins, enhancing phagocytosis.
