phagocytosis


« Back to Glossary Index

This is the internalisation of particulate matter by cells. Usually the phagocytic cells are macrophages or neutrophils and the particles taken up are bacteria. The ingested material is contained in a vesicle called a phagosome which fuses with a lysosme to form a phagolysosme. The lysosomal enzymes are important in destruction of the pathogen.
