Phagocytosis - Wikipedia
网页Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat' and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome.

网页2022年7月10日 · Phagocytosis is a type of endocytosis whereby a cell engulfs a particle in an internal compartment- the phagosome. The cell rearranges its membrane to surround and internalise the target particle. Phagocytosis is a major mechanism for detecting and removing potentially pathogenic material.

网页2020年4月17日 · Phagocytosis is the ingestion of extracellular particulate material such as invading pathogens or dead/dying cells by phagocytic cells and is one of the important innate defense mechanisms. It is primarily conducted by specialized cells, such as macrophages, neutrophils, and dendritic cells.
Phagocytosis- definition, mechanism, steps with example
网页2022年5月1日 · What is phagocytosis? Phagocytosis is a process by which cells ingest large particles (> 0.5 micrometers) into membrane-bound vesicles called phagosomes, which are then targeted to the lysosomes for enzymatic degradation. Phagocytosis is greatly enhanced by the opsonization of the bacteria.
