Across
  1. 1. Promotes inflammation and allergic reactions
  2. 4. Most common Ig. Defend against bacteria, viruses, and toxins. Passes placenta from mom to baby
  3. 8. Agents that cause disease
  4. 9. Artificially and naturally acquired immunity (Ready-made antibodies or antitoxin are injected, antibodies are passed to baby from mom)
  5. 12. Activate other T-cells and B-cells and macrophages
  6. 13. Antibodies and cytotoxic T-cells
  7. 15. Provided by lymphocytes
  8. 16. Activates B-cell
  9. 17. Protects uninfected cells by blocking viral reproduction
  10. 19. Immune response against a harmless substance
  11. 21. Attach to antigen, presents it to a helper T-cell. Once activated by T-cell, ____ divides
  12. 23. Enzymes, Interferons, Defensins
  13. 24. Proteins that react with foreign antigens. Inhibit viral replecation by attaching to antigens. Mark pathogens for destruction by phagocytes
  14. 26. Response to trauma, infection, heat, or chemicals. Brings more phagocytic cells which remove cell debris and pathogens
  15. 27. Protiens that damage bacterial cell membranes
  16. 29. Destroy infected cells by stimulating apoptosis. Responsible for rejection of organ transplants
Down
  1. 2. Lysozymes in tears and saliva, pepsin in the stomach kills bacteria
  2. 3. First to respond to infection, most numerous phagocytes.
  3. 4. Found in body secretions (i.e. tears, saliva, breast milk). Prevents pathogens from entering body
  4. 5. Found in skin. Phagocytize invading organisms, present antigen to helper T-Cell, activate T-cell
  5. 6. Kill cancer and virus infected cells before lymphocytes are activated
  6. 7. Elevated Body temperature in response to microbial infection
  7. 10. Species are immune to diseases of other species
  8. 11. Artificially or naturally acquired immunity (Vaccine, immunity develops after exposure to a pathogen, resistance follows infection)
  9. 14. Barriers that prevent the entrance of some pathogens. (i.e. skin and mucous)
  10. 18. Work with memory T-cells to activate the immune response faster
  11. 20. B-cell sometimes divides into _____ _____ that produce antibodies
  12. 22. Produced after initial exposure to antigen. Will immediately produce cytotoxic T-cells if re-exposed to the antigen. Pathogen is usually destroyed before illness occurs.
  13. 25. First to reach site of infection, reacts to bacteria, viruses, and mismatched blood
  14. 28. Resistance to pathogens or their toxin
