Lymphatic System

3. fights invaders that get past innate defenses by mounting an attack one or more specific foreign substances
8. nonspecific response triggered whenever body tissues are injured
10. chemicals secreted by WBC's and macrophages exposed to foreign substances, make your temp go up
11. when lymphocytes defend the body (protected by living cells)
13. engulf and destroy pathogens that breach surface membrane barriers
14. aggressive lymphocytes that can burst and kill cancer cells, virus-infected body cells and nonspecific targets before the adaptive system
18. congential and acquired conditions in which the production or function of immune cells or complements is abnormal
20. when the body produces antibodies that attack its own tissues
22. produce antibodies and oversee humoral immunity
24. any substance capable of provoking an immune response
25. molecules that are recognized as self and do not cause an immune response in us

1. soluble proteins secreted by B cells or plasma cells in response to an antigen
2. responds immediately to protect the body from all foreign things
4. small proteins secreted by virus-infected cells to help defend cells not yet infected
5. provided by antibodies present in the body's "humors" or fluids
6. short-lived immunity from the introduction of donated antibodies
7. group of at least 20 plasma proteins that circulate in the blood in an inactive state, then attach to foreign things to fight them
9. B cell clones that are not plasma cells, capable of responding to the same antigen if they "see" it again
12. cell-mediated arm of adaptive defenses, eliminate specific foreign substances
15. abnormally vigorous immune responses when the immune system causes damage to body tissues as it fights the "threat"
16. immunity produced by an encounter with an antigen
17. B cell clones, produce highly specific antibodies at a very fast rate
19. capable of responding to a specific antigen by binding to it with antigen-specific receptors on the lymphocyte
21. inside lymph, engulf and destroy foreign things in the lymph
23. harmful microorganisms
