Across
- 2. Expands production of specific B and T cells

- 6. Memory elicits this prolonged protection to a pathogen
- 8. Rapid response to a pathogen that the body has previously been exposed to
- 9. Causes a specific immune response
- 10. Enzyme in tears and saliva that kill bacteria
- 12. Substance in the respiratory system that sticks to pathogens
- 14. Immune response to a harmless substance
- 16. Y-shaped proteins that recognize antigens in circulation
- 17. White blood cells that facility specific immunity
- 19. Antibody-mediated immunity in bodily fluids
- 22. Protective barrier covering the body
- 23. Cells that act immediately to destroy an antigen
- 27. Phagocytes that comprise a large percent of circulating white blood cells and ingest foreign substances
- 29. A person's immune system attacks their own cells and tissues
- 32. Weak or harmless pathogen that can be injected to produce immunity
- 33. Destroys pathogen-infected cells
- 34. Destroy virus infected cells and cancer cells
Down
- 1. Line the respiratory tract to sweep mucus with pathogens out of the lungs
- 4. Remain in the body to respond quickly to a second infection with the same pathogen
- 5. Lymphocytes that mature in the bone marrow
- 7. Lymphocytes that mature in the thymus
- 9. Serious systemic immune response
- 11. Higher body temperature
- 13. Cell-mediated response effector cells that destroy viral-infected cells
- 15. Virus that infects helper T cells
- 18. Proteins that poke holes in pathogens so water enters and the cell bursts
- 20. Programmed cell death
- 21. Viral-infected cells produce this cytokine
- 24. Large eating cells in the tissues that ingest small pathogens
- 25. Phagocytes that act as antigen presenting cells
- 26. Basophils and mast cells release this molecule which causes dilation in blood vessels
- 28. Induces heat, redness, swelling and pain
- 30. Activate other immune cells to initiate the immune response
- 31. Effector B cells that secrete antibodies
