Across
- 1. second line of defense, causes swelling and redness
- 5. A living or non-living agent that causes disease
- 7. dilate blood vessels and cause cells to move into the tissue
- 8. A substance that produces an immune response without causing disease
- 10. type of t cell that destroy the body cells that have been infected with a pathogen
- 11. type of infection that causes the host cell to burst
- 13. Unique protein molecules found on the surface of cells and viruses that are use to communicate identity and trigger and immune response
- 15. immunity provided by getting exposed to a pathogen (ie vaccines)
- 16. cells that engulf pathogens
- 17. scientist's experiments using broth and swan necked flasks led to a theory that proposed microorganisms cause disease
Down
- 2. heats up your body and makes it difficult for pathogens to reproduce
- 3. chemicals that kill or slow the growth of bacteria
- 4. An organism that transfers a pathogen from one host to another.
- 6. type of b cells are responsible for remembering antigens for future infections
- 8. disease in which the body attacks healthy cells instead of pathogens
- 9. causes disease by taking over the reproductive machinery of healthy cells and turns them into pathogen-producing factories
- 12. identifies antigen for destruction causing clumping or marking for macrophages
- 14. introduces a small amount of inactive pathogen into the body to create immunity
