phagosome

 [fag´o-sōm]
a membrane-bound vesicle in a phagocyte containing the phagocytized material.

phag·o·some

(fag'ō-sōm),
A vesicle that forms around a particle (bacterial or other) within the phagocyte that engulfed it, separates from the cell membrane, and then fuses with and receives the contents of cytoplasmic granules (lysosomes), thus forming a phagolysosome in which digestion of the engulfed particle occurs.
[phago- + G. sōma, body]

phagosome

/phago·some/ (fag´o-sōm) a membrane-bound vesicle in a phagocyte containing the phagocytized material.

phagosome

(făg′ə-sōm′)
n.
A membrane-bound vesicle found in a cell by an inward folding of the cell membrane to hold foreign matter taken into the cell by phagocytosis.

phagosome

[fag′əsōm]
a membrane-bound cytoplasmic vesicle within the phagocyte that engulfs it. The vesicle contains phagocytized materials and may fuse with a lysosome, forming a phagolysosome within which the lysosome digests the phagocytized material. Also called phagocytic vacuole.

phagosome

The vacuole, formed within a PHAGOCYTE, that surrounds material that has been taken up by cell membrane invagination. A phagosome may fuse with a lysosome to provide digestive enzyme.
