  1. What is the difference between the E. coli that lives in your large intestine and produces vitamins for you, and the E. coli that causes internal bleeding, diarrhea, and dehydration?
    • The pathogenic strain differs anatomically.
    • The pathogenic strain differs genetically.
    • The bacteria is only pathogenic in certain environments.
    • The pathogenic strain is infected with a virus.

  2. The body is invaded by a pathogen. The pathogen must get past the defenses of the body in what order?
    • Nonspecific internal defenses, specific internal defenses, external barriers
    • Nonspecific internal defenses, external barriers, specific internal defenses
    • External barriers, specific internal defenses, nonspecific internal defenses
    • External barriers, nonspecific internal defenses, specific internal defenses

  3. You have a tickle in your nose and you sneeze. This is your bodys response to:
    • White blood cells attacking a foreign invader and accumulating in your nose.
    • The reflex of a foreign particle going down the esophagus and getting digested in the stomach.
    • A foreign particle getting caught on the cilia in your nose or throat.
    • A foreign particle getting caught on the lysozymes in your nose or throat.

  4. What is the relationship between phagocytes, leukocytes, macrophages, neutrophils, and natural killer cells?
    • All are different names for the same type of white blood cell.
    • All are natural killer cells that have different jobs in the nonspecific internal defense.
    • All are white blood cells. Natural killer cells are a type of phagocyte or leukocyte. Macrophages and neutrophils are other kinds of white blood cell.
    • All are white blood cells. Macrophages and neutrophils are types of phagocytes. Natural killer cells are another kind of white blood cell.

  5. When a person has an allergic reaction to poison ivy and their legs swell up, how would they benefit from taking an antihistamine?
    • It would induce a fever and, as a result, reduce swelling.
    • It would reduce the amount of fluid leaking from the capillaries in the legs and reduce swelling.
    • It would increase the flow of blood to the legs, bringing more white blood cells to the area and an enhanced specific immune response.
    • It would invoke an inflammatory response, releasing chemicals that promote healing of the tissue.

  6. When you have a fever, are you exhibiting a specific immune response?
    • No. Fever is not part of the specific immune response.
    • No, but fever is necessary to induce a specific immune response.
    • Yes. Fever is the first stage of the specific immune response.
    • Yes. Fever is the last stage of the specific immune response.
