Across
  1. 2. The immune systems response type when first introduced to an antigen
  2. 3. Receptors on host cells that can bind to PAMPs
  3. 4. Cell type responsible for producing antibodies
  4. 7. Type of selection where T and B cells are produces in response to an antigen
  5. 9. Immune response that is constant and the first line of defense
  6. 11. Cell type that responds to the presence of antigens
  7. 12. The ability of an organism to fight disease
  8. 13. Cell surface B-antigen receptors that can bind to antigens
  9. 16. Structure on foreign microbes but not host cells
  10. 19. Stem cell type that is the precursor to every blood cell
  11. 20. Immunity where antibodies are produced independently in response to antigen presence
Down
  1. 1. Engulf and destroy pathogens in the body
  2. 3. Immunity type where people are given antibodies from another
  3. 4. Inner tissue of bone responsible for producing blood cells
  4. 5. Circulation type where clear lymph fluid moves throughout the body
  5. 6. Infectious organism that can cause disease
  6. 8. Toxic substance that induces an immune response
  7. 10. Signal molecules produced when the immune system is activated.
  8. 14. Immune Response Immune response that isn't constant and changes over time.
  9. 15. Cell type that can launch a much more intense response to an antigen when previously exposed to it
  10. 17. Response type when the immune system has previously been exposed to an antigen
  11. 18. Immunity gained without induction of disease
