Adaptive Immune System
Across
- 6. the ability to resist an infection before symptoms appear
- 7. a type of innate defense; includes skin and mucus membranes
- 8. the process by which a macrophage engulfs a pathogen
- 11. protein markers on the outside of our cells as well as pathogens; can be familiar or foreign
- 13. "big eaters;" engulf pathogens and display their antigens
- 15. created by B-cells; bind to antigens, blocking the pathogen from infecting more host cells
- 16. B-cells that last a long time and continue to produce antibodies against a pathogen
- 17. where B-cells and T-cells are produced; where B-cells mature
- 20. activated by macrophages displaying foreign antigens; release cytokines to activate B-cells and cytotoxic T-cells
- 22. activated by cytokines; release perforins to destroy infected cells
Down
- 1. where B-cells and T-cells are stored
- 2. released by cytotoxic T-cells to destroy infected body cells
- 3. a type of innate defense; includes macrophages, natural killer cells, inflammation, proteins, and fever
- 4. "disease-producer;" any organism or agent that can produce disease
- 5. immune response that is the major process of the adaptive immune response; executed by B-cells; destroys the pathogen and prevents future infection by the same pathogen
- 9. the immune response that includes barriers and internal defenses; non-specifically attempts to prevent all pathogens from causing infection
- 10. released by helper T-cells; activate B-cells and cytotoxic T-cells
- 12. where T-cells mature
- 14. B-cells and T-cells
- 15. the immune response which is the body's 3rd line of defense; targets one specific pathogen at a time
- 18. lymphocytes that create antibodies
- 19. the immune response that is major process of the adaptive immune response; executed by cytotoxic T-cells; destroys the pathogen and deals with infected body cells
- 21. another term for the adaptive immune response
