Phagocytosis is a type of endocytosis in which a cell encloses large particles in a phagocytic vesicle called phagosome and engulfs them.
The process of phagocytosis involves the folding of the plasma membrane around the substance that is being engulfed and the subsequent formation of a membrane vesicle called Phagosome. This phagosome fused with the primary lysosome to form secondary lysosome. The material is digested by the hydrolytic enzymes present in the secondary lysosomes.
