What is phagocytosis in regard to the immune system of humans?

Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
