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