Phagocytosis refers to the process by which certain living cells called phagocytes engulf other cells or particles.
Phagocytosis process occurs mostly when the cell is trying to destroy a kind of virus or infected cell, and is used by the immune system. The phagocyte cells protect the human body by ingesting harmful particles like viruses, bacteria, and other infected or dying cells. Phagocytosis plays a different role for different types of cells, from ingestion of food to destruction of particular cells. Until the cell is not physically in touch with the particle it wants to engulf, the process of phagocytosis does not take place.
Phagocytosis is a vital aspect of the immune system. Phagocytosis is performed by different cells of the immune system, like neutrophils, macrophages and dendritic cells. The function of phagocytosis in the immune system is to kill pathogens like bacteria and viruses, and infected cells. By destroying the pathogens, the immune system stops the spread of infected cells and the disease.
