PNP 102 Ch 33 Immune System

2. cell surface proteins that match an individual’s own genetic code or assist the immune system to identify foreign molecules.
4. white blood cells that engulf and digest bacteria and foreign material.
6. type of cytokines that attracts neutrophils and monocytes to remove debris, promotes the maturation of more T cells when they detect antigens, and directs B-cell lymphocytes to multiply and mature.
7. immunity that occurs as a direct result of infection by a specific microorganism.
9. chemical substances that destroy foreign agents such as microorganisms.
11. large phagocytes present in tissues such as the lungs, liver, lymph nodes, spleen, and peritoneum.
13. immediate but short-lived immunity that develops when ready-made antibodies are given to a susceptible individual.
15. immune process in which many different proteins are activated in a chain reaction when an antibody binds with an antigen.
16. foreign substance that induces an immune response.
17. formation of antibodies
18. white blood cells with immune functions.

1. immunity that results from the administration of a killed or weakened microorganism or attenuated toxin.
3. structures that maintain immunocompetence, the ability to cooperatively protect a person from external invaders and the body’s own altered cells.
5. process that occurs when T cells survey proteins in the body, actively analyze the surface features, and respond to those that differ from the host by directly attacking the invading antigen.
8. phagocytes present in blood that migrate to tissue as necessary to ingest small-sized debris.
10. proteins produced by B lymphocyte plasma cells that bind with antigens and promote the destruction of invading cells; also known as antibodies.
12. inability to mount an immune response.
14. target-specific system of defense against infectious, foreign, or cancerous cells carried out primarily by lymphocytes.
