  1. 3. A category that covers neutrophils, basophils, and eosinophils.
  2. 7. Part of the adaptive immune system, solves the hiding virus problem by committing suicide.
  3. 9. Protein that neutrophils makes and stores in order to rapidly mobilize to its surface.
  4. 10. Antibodies are produced by.
  5. 13. Regulates, keeps immune system from overreacting or reacting inappropriately.
  6. 14. Very short lived, not antigen presenting, can also damage our own healthy cells.
  7. 16. Produces antibodies and targeting pathogens in the body fluids. Lymphocyte.
  8. 17. A stage of macrophage activation where the macrophage is patrolling and garbage collecting.
  9. 19. A stage of macrophage activation where the macrophage has upregulaed expression of class II MHC.

  1. 1. When a person's own immune response is induced from exposure to a pathogen.
  2. 2. Secretes chemical messengers called cytokines; cytokine factories.
  3. 4. A system in which its output helps to amplify the input.
  4. 5. Functions as "billboards" to inform killer T cells that something is going wrong in the cell.
  5. 6. Vesicle containing an invader during phagocytosis.
  6. 8. A stage of macrophage activation in which the macrophage is larger and has an increased rate of phagocytosis.
  7. 11. A carbohydrate that is found on many common pathogens.
  8. 12. "Billboards" that put the actual bacterial proteins on display.
  9. 15. The amount of proteins the complement system consists of.
