Across
- 2. an antigen that is not disease causing given to people in order to elicit a primary immune response and to make memory cells.
- 4. cell Type of B and T cells produced that give the body immunity to future exposures to a pathogen.
- 5. ________ immune response. The first time a pathogen is encountered.
- 6. created when a critical percentage of humans in a population exhibit immunity to a pathogen
- 10. organs in which lymph is filtered and acted upon by white blood cells and lymphocytes.
- 11. Differentiated B-cells that produce antibodies specific to an encountered antigen.
- 13. Specific molecules or parts of pathogens that the immune system recognizes as targets.
- 17. The body's first line of defense providing a non-specific response to pathogens through physical, chemical, and cellular defenses.
- 21. aka white blood cells.Cells that search for, attack, and destroy germs to keep the body healthy. They are crucial components of both innate and adaptive immune responses.
- 25. named after bone marrow. Specific, have antibodies on cytoplasm for antigen recognition
- 27. Non-specific first lines of defense including skin, mucus membranes, non-specific white blood cells etc.
- 29. cell that is part of the lymphatic system, especially T and B cells
- 30. Small structures that filter and destroy germs to prevent them from spreading to other parts of the body. They contain immune cells that analyze foreign invaders.
- 31. Located in the throat, they trap foreign invaders such as bacteria and viruses.
- 32. Part of the long-term memory of the immune system, quickly producing antibodies upon re-exposure to an antigen.
Down
- 1. Developed after exposure to a pathogen or antigen, leading to immunological memory, either naturally or through vaccination.
- 3. Retain memory of pathogen-specific information for rapid response to the same pathogen upon re-exposure.
- 4. Retain a memory of specific pathogens to enhance the speed and efficacy of the immune response upon re-exposure.
- 7. Central to adaptive immunity, including T-cells and B-cells, which have specific roles in immune defense.
- 8. An organ that stores white blood cells and filters the blood, destroying old and damaged red blood cells.
- 9. Involves the transfer of ready-made antibodies from one individual to another, providing temporary immunity.
- 10. fluid from tissue that flows in lymph vessels
- 12. Provides a targeted response to specific pathogens, features memory components, and develops over time.
- 14. _________ immune response. The second or greater time a pathogen is encountered. Memory cells help out a lot.
- 15. Capable of killing infected cells directly.
- 16. protein or carbohydrate that is unique and recognized by immune cell receptors and antibodies
- 18. Famous white blood cell that is a main antigen presenting cell. It's name means big eater.
- 19. Include dendritic cells, macrophages, and B-cells that process and present antigens to T-cells.
- 20. means cell eating. Macrophages do it a lot.
- 22. protein produced by plasma cells that mark and neutralize pathogens by attaching to antigen
- 23. organism that causes disease
- 24. _______ response. Causes swelling and increased blood flow
- 26. includes lymph, lymph vessels and lymph nodes
- 28. Molecules displayed on cell surfaces that present antigenic peptides to T-cells.
