Phagosomes

A phagosome is formed when a phagocyte engulfs a particle. The phagocyte binds the antibodies on the cell surface of the phagocytic cell by specific Fc receptors. This triggers the psuedopods of the phagocytic cell to elongate around the cell until they fuse at their tips. This vesicle is known as a phagosome .

A phagosomes purpose is primaraly to aid the degradation of the particals that are within it (often pathogenic particals), that have been engulfed during Phagocytosis .
