Across
  1. 2. found in all tissues, engulf pathogens, travel to lymph nodes to activate T cells
  2. 5. Occurs when individual receives another person’s antibodies
  3. 6. Occurs when individual creates their own immunity
  4. 9. capability of removing/killing pathogens, foreign substances & cancer cells
  5. 11. tiny close-ended vessels that are found throughout body & take up excess interstitial fluid
  6. 12. form a one way system that carries lymph
  7. 13. T cells mature & learn to recognize combinations of self-molecules & foreign molecules
  8. 15. where lymphocytes develop & mature (______ lymphoid organs)
  9. 16. Contains mostly red pulp that filters & cleanses blood
  10. 17. cytokines that affect the behavior of other cells
  11. 19. fluid inside the capillaries & vessels
  12. 20. Recognize & respond to antigens presented by various types of cells
  13. 21. large lymphocytes that kill virus-infected cells & cancer cells
Down
  1. 1. use of vaccines to achieve immunity
  2. 3. “Acquired Immunity”
  3. 4. Where all blood cells are produced including lymphocytes
  4. 7. fully functional immunity without previous exposure to invaders
  5. 8. receptor protein in plasma membrane allowing cells to combine with antigen
  6. 10. Recognize & respond to antigens only presented by specialized antigen-presenting cells
  7. 14. Long living & great in numbers so when the same antigen is presented again, immune response is rapid
  8. 18. where some lymphocytes are activated by antigens (______ lymphoid organs)
