How do phagocytes protect the body
Olin [163]

1) pathogen enters body and releases chemoattractants

2) a phagocyte/macrophage is attracted by these chemicals

3) the phagocyte engulfs the pathogen using its pseudopodia

4) the membranes of both organisms fuse forming a phagosome

5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome

6) these enzymes digest the pahogen (hydrolyse the bonds)

7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)
