  1. 5. The white blood cell responsible for humoral immunity.
  2. 7. The type of immunity characterized by using pre-existing antibodies rather than producing new ones.
  3. 9. A blood protein that responds to and counteracts a specific pathogen.
  4. 10. A component of the innate immune system made in the liver that promotes inflammation and enhances the ability of antibodies and phagocytes.
  5. 12. Proteins naturally produced by the body that the immune system recognizes.
  6. 14. A protein released by animal cells, usually in response to the entry of a virus, that inhibits virus replication.
  7. 16. The kind of immunity where instead of antibodies, it involves the direct activation of phagocytes, T-cells and cytokines.
  8. 17. A cell that engulfs and absorbs bacteria and other small cells.
  9. 18. A lymphocyte produced by the thymus that actively participates in immune responses.
  10. 22. An immune response by the body caused by a substance, usually a pollen, fur, or food, to which it becomes hypersensitive.
  11. 24. cells Long lived lymphocytes that respond to a particular antigen upon reintroduction.
Down
  1. 1. A state where the immune system is weakened, damaged, or absent, making the body unable to fight disease.
  2. 2. The lymphocyte that's able to bind to certain tumor cells or pathogens without stimulating antigens.
  3. 3. A normal, healthy immune response or system.
  4. 4. "Big eaters"; or large phagocytes found at sites of infection.

  10. 17. A substance produced by bacteria that causes a fever when introduced into the blood.
  11. 19. The kind of immunity from the adaptive immune system that defends against pathogens in body fluids (or humors).
  12. 20. The body's immediate, non-specific, protective response against injury or infection.
  13. 21. A long-lasting kind of immunity where your body produces antibodies after exposure to a pathogen.
  14. 23. The kind of disease caused by when the immune system mistakenly attacks its own healthy cells.
