  1. 1. stimulate development of adaptive immunity in cells that contact the environment, agranulocytes.
  2. 5. found on potential pathogens
  3. 6. innate defenses in vertebrates also involve natural killer cells, a type of lymphocyte.
  4. 7. Hemocytes also release ...that disrupt the plasma membranes of fungi and bacteria.
  5. 12. discharge destructive enzymes, granulocytes
  6. 14. found on innate immune cells

  4. 8. circulate in the blood and are attracted by signals from infected tissues, granulocytes
  5. 9. traps and allows for the removal of microbes.
  6. 10. a fluid rich in white blood cells, dead pathogens, and cell debris from damaged tissues.
  7. 11. is a life-threatening condition caused by an overwhelming inflammatory response
  8. 13. pH of skin and the digestive system prevents growth of many bacteria.
