phagocytosismedical dictionary

<cell biology> Endocytosis of particulate material, such as microorganisms or cell fragments. The material is taken into the cell in membrane bound vesicles (phagosomes) that originate as pinched off invaginations of the plasma membrane. Phagosomes fuse with lysosomes, forming phagolysosomes in which the engulfed material is killed and digested.

Origin: L. Phagedaena, Gr Phago, To eat.
