Chapter 1

3. a process that enhances phagocytosis by coating the pathogen
4. a study of the cellular and molecular events that occur after an organism encounters microbes and other foreign molecules
7. the ability of the lymphocyte repertoire to recognize a very large number of antigens
8. host immune defense against microbes in the first few hours or days after infection
9. host immune defense develops as a response to infection and adapts to infection
11. the theory proposed by Paul Ehrlich
14. protection from disease
15. cells that mediate the ultimate effect of the immune response
18. immunity achieved by transferring antibodies from an immunized individual to an unimmunized person

1. cells that mediate the adaptive immune response
2. collective and coordinated response to the introduction of foreign substances
5. immunologic unresponsiveness
6. molecules secreted by the humoral immune system
10. a process that involves recruitment of phagocytes and leukocytes to destroy the microbes
12. cytokines that regulate cell migration and movement
13. a molecular entity that is recognized by the immune system
16. part of a complex antigen that specifically is recognized by lymphocytes
17. immunologically inexperienced
