  33. innate or nonspecific resistance

    Cells : 
    Involved in phagocytosis and production of chemicals 
  34. Adaptive/aquired/specific immunity

    ability to recognize a particular substance
  35. Adaptive/aquired/specific immunity

  42. humoral response:
    antibodies defend against infection in body fluids 
  43. cell mediated response
    cytotoxic lymphocytes defend against infection in the body cells
  44. what is adaptive immunity
    involves the ability to recognize, respond to, and remeber a particular substance 
  45. what are the 2 types of adaptive immunity
    • humoral or antibody - mediated: B Cells
