  2. 11. test that healthcare professionals use to see composition of cells in blood
  3. 14. most common assault to the immune system
  4. 15. 2 layers on a cell that separate the inside of the cell from the outside of the cell
  5. 17. body system that our immune cells flow in and out of through ducts and capillaries
  6. 18. type of memory that some cells retain after seeing a type of pathogen
  7. 21. % of total blood volume
  8. 25. heaviest layer of blood made solely of red blood cells
  9. 26. type of selection to let the body know which B-cells to make more of
  10. 31. when an antibody is assembled by picking gene segments and pasting them together
  11. 32. type of cell with no granules that circulates in the blood. Macrophages and dendritic cells
  12. 34. special proteins that circulate the blood of immunized people
  13. 35. type of cells that stick around as “leftovers” and are easier to activate
  14. 36. protein that spans the cell membrane
  15. 38. condition that results in low hemoglobin
  16. 40. type of T-cell that directs the action and are cytokine factories
  17. 41. eukaryotic pathogen can be unicellular or multicellular
  18. 45. each virus has its own unique set of what?
  19. 46. a tightly controlled process to create specialized cells from unspecialized cells
  20. 49. lineage that creates red blood cells, platelets, myoblasts, and monocytes
  21. 50. the study of the immune system
  22. 51. what fungi cell walls are made of
Down
  1. 1. largest invader
  2. 3. type of cell that helps us to deal with larger parasites
  3. 4. cell that lives in tissues on watch for chemical signals from injured cells or pathogens
  4. 5. Prokaryote, second smallest pathogen
  5. 6. type of cell that lives in the tissue and responds to invaders via phagocytosis
  6. 7. smallest non-living pathogen
  7. 8. immune response that is 2nd line of defense after skin. Mounts a response to a variety of well-known pathogens
  8. 9. top, least dense layer of blood that contains proteins, nutrients, and hormones
