Phagocytosis Step-Through
Step 1 of 5
Ly MHC II Chemotaxis
Step 1 — Chemotaxis
The phagocyte detects chemical signals released by infected or damaged tissue and moves toward the pathogen.
Chemokines create a concentration gradient. Neutrophils and macrophages have receptors that allow them to follow this gradient to the infection site.
