What is Phagocytosis ??

👍It is the process by which certain living cells called phagocytes ingest or engulf other cells or particles.

👍The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell.

👍In some forms of animal life, such as amoebas and sponges, phagocytosis is a means of feeding.

👍In higher animals phagocytosis is chiefly a defensive reaction against infection and invasion of the body by foreign substances (antigens).
