Phagocytosis in three steps: 1. Unbound phagocyte surface receptors do not trigger phagocytosis. 2. Binding of receptors causes them to cluster. 3. Phagocytosis is triggered and the particle is taken up by the phagocyte.

In cell biology, phagocytosis (fromAncient Greek φαγεῖν (phagein), meaning "to devour", κύτος, (kytos), meaning "cell",and -osis, meaning "process") is the process by which a cell—often a phagocyte or a protist—engulfs a solid particle to form an internal vesicle known as a phagosome. Phagocytosis was first noted by Canadian physician William Osler, and later studied by Élie Metchnikoff.
