In addition, macrophages play an important role in eliminating diseased and damaged cells through their programmed cell death.

Detailed explanation-4: -Phagocytosis and Killing of Bacteria by Professional Phagocytes and Dendritic Cells-PMC.

Detailed explanation-5: -They are a key component of the innate immune system. There are three main groups of phagocytes: monocytes and macrophages, granulocytes, and dendritic cells, all of which have a slightly different function in the body.
