Across
  1. 2. overreaction to an allergen antigen
  2. 5. clear fluid; in lymphatic vessels
  3. 8. "killer" T Cell attaches to some antigen bearing cells and destroys directly
  4. 9. vessel caries lymph into node
  5. 11. body invader; bacteria, virus, fungi
  6. 12. antigen-binding; produced by plasma B cells; fights many pathogen
  7. 14. vessel caries lymph away from node
  8. 15. where blood vessels enter node
  9. 18. gland; lower neck region; T cell maturation
  10. 19. vessel vessel; transports lymph
  11. 20. T Cell/B Cell saves antigen shape; multiplies readily when antigen is present again; lasts a lifetime
Down
  1. 1. defense cells; mature in bone marrow
  2. 2. defense precise; lymphocytes; antigen/antibody
  3. 3. defense broad, nonspecific defense; mechanical barriers, chemical barriers, fever, inflammation, phagocytosis
  4. 4. antigen (but not whole pathogen) is introduced creating memory cells
  5. 6. cell WBC; produces antibodies
  6. 7. WBC; makes antibodies
  7. 9. lymphocytes recognize self antigens as pathogen antigens
  8. 10. protein in cell wall; marker/sign
  9. 13. contamination by pathogen
  10. 15. T Cell creates cytokines that activates T and B cells
  11. 16. large; behind stomach; produces lymphocytes, filters the blood, stores blood cells, destroys old blood cells
  12. 17. defense cells; mature in thymus
