Problem 8

Background and context

Phagocytes and antigen-presenting cells are immune system cells that participate in the phagocytosis process.

The phagocyte engulfs the foreign cell, generating the phagosome, which subsequently merges with the lysosome to form the phagolysosome. The hydrolyzing enzymes of the lysosome then operate on it, digesting the alien cell.

Antigen-presenting cells are immune cells that recognize, engulf, and alert the adaptive immune system to an infection.
