| Front | How does phagocytosis work? |
|---|---|
| Back | - phagocyte attracted to pathogen by chemotaxis - phagocyte receptors bind to pathogen antigens - pseudopodia extend around pathogen, engulfing it in phagosome (vesicle) - lysosomes migrate towards and fuse with phagosome (NOT EXOCYTOSIS) - lysozymes hydrolyse cells or bacterial cell walls - soluble products absorbed into cytoplasm - indigestible products egested |
