Steps of Phagocytosis

Step 1

Chemotaxis: phagocytes are attracted to microorganisms. Adherence: phagocyte's membrane sticks to surface of microorganism.

Step 3

Formation of phagosome: pseudopods meet and fuse around microorganism

Step 6

Formation of residual body containing indigestible materials

Step 2

Ingestion: membrane of phagocyte (pseudopods) engulfs microorganisms

Step 5

Phagolysosome enzymes digest the ingested microbes

Step 4

Phagosome and lysosome membranes fuse to form a phagolysosome

Step 7

Residual body discharges waste materials
