dedicated to defense, these form... - (ANSWER)the immune system
protective/adaptive immunity takes time to develop while
________________________ can _________ _______- and cause disease -
(ANSWER)microorganisms can rapidly multiply
Immunity involves two responses: - (ANSWER)1. Flexible but specific defenses of
the adaptive immune response
2. Fixed defenses of the innate immune response
In adaptive = - (ANSWER)B and T cells

cell sources
Some microbes are ________ and even __________ (ex:_____________) -
(ANSWER)some are harmless and helpful
ex: E. Coli
What is protecive immunity? - (ANSWER)People who survive a specific infection
become immune to it
To provide protective immunity, the immune system must first -
(ANSWER)engage the microorganism

(ANSWER)-1000
-Commensal bacteria (eat at the same table. Not harmful)
What is first line of external defense against infection? - (ANSWER)skin - it is a
tough impenetrable barrier
If a disease shares the same _________ (like smallpox and cowpox) you can use
one or the other to create a vaccination - (ANSWER)epitope
Mucosal surfaces are bathed in mucus; thick fluid containing
