phagocytosis
phagocytosis The process by which a cell membrane can invaginate and enclose externally derived, solid material within a vacuole, without disrupting the continuity of the cell surface. Subsequently this vacuole will fuse with a lysosome and its contents will be wholly or partly digested. Although phagocytosis is a feature of animal cells, bacteria may be attacked by phagocytotic cells. The capsule may afford them some protection against such an attack.

phagocytosis
phagocytosis The process by which foreign particles invading the body or minute food particles are engulfed and broken down by certain animal cells (known as phagocytes). The plasma membrane of the phagocyte invaginates to capture the particle and then closes around it to form a sac or vacuole. The vacuole coalesces with a lysosome, which contains enzymes that break down the particle. See endocytosis. Compare pinocytosis.

phagocytosis
phagocytosis A form of endocytosis in which a cell membrane invaginates and encloses externally derived, solid material within a vacuole, without disrupting the continuity of the cell surface. Subsequently this vacuole will fuse with a lysosome and its contents will be wholly or partly digested.
