  • Enzyme released onto pathogen in a phagosome (5)
  • Most common type of phagocyte (10)
  • Process of engulfing a pathogen (12)
  • Protein (released by t-helper cells) that stimulates other cells to produce memory cells (9)
  • The "umbrella term" for all white blood cells (10)
  • These cells help the immune system to respond quickly if the same pathogen invades the body again (6, 5)
  • Where macrophages are produced (4, 6)
