Immune System

3. medicines that fight bacterial infections in people and animals
7. specific lymphocytes that produce antibodies as part of the adaptive immune response.
10. Any substance that causes the body to make an immune response against that substance.
13. mean by which the body is given immunity to a disease by intentional exposure to small quantities of it.
15. acquired from exposure to the disease organism through infection with the actual disease.
17. nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals:
19. responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies
20. type of immune cell that can surround and kill microorganisms, ingest foreign material, and remove dead cells.

1. results when exposure to a disease organism triggers the immune system to produce antibodies to that disease.
2. happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them.
4. provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
5. cell produced through hematopoiesis and found mainly in the blood
6. white blood cells that play a central role in the adaptive immune system, where the body adapts specificity to foreign antigen
8. act of introducing a vaccine into the body to produce protection from a specific disease.
9. protein made by plasma cells (a type of white blood cell) in response to an antigen
11. type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.
12. physical and chemical barriers that are always ready and prepared to defend the body from infection
14. lymphocytes known as B cells and T cells.
16. key player of the adaptive immune response that is responsible for humoral immunity in mammals.
18. type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue.
