Immune System

2. type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.
5. provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
6. specific lymphocytes that produce antibodies as part of the adaptive immune response.
9. mean by which the body is given immunity to a disease by intentional exposure to small quantities of it.
12. type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue.
13. nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals:
14. protein made by plasma cells (a type of white blood cell) in response to an antigen
15. responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies
17. key player of the adaptive immune response that is responsible for humoral immunity in mammals.
18. happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them.
19. medicines that fight bacterial infections in people and animals
20. acquired from exposure to the disease organism through infection with the actual disease.

1. physical and chemical barriers that are always ready and prepared to defend the body from infection
3. Any substance that causes the body to make an immune response against that substance.
4. cell produced through hematopoiesis and found mainly in the blood
7. results when exposure to a disease organism triggers the immune system to produce antibodies to that disease.
8. act of introducing a vaccine into the body to produce protection from a specific disease.
10. white blood cells that play a central role in the adaptive immune system, where the body adapts specificity to foreign antigen
11. lymphocytes known as B cells and T cells.
16. type of immune cell that can surround and kill microorganisms, ingest foreign material, and remove dead cells.
