, adaptive immune responses closely interact withAnswer: innate immune responses
immune system INNATE IMMUNITYAnswer: barrier defenses, cellular and molecular
defenses
immune system ADAPTIVE IMMUNITYAnswer: adaptive defenses, cellular response,
humoral response
adaptive immune system is subdivided into 2 branchesAnswer: cellular response, humoral
response
cellular responseAnswer: t cell-mediated immunity
humoral responseAnswer: antibody-mediated immunity
cell mediated destroyAnswer: cells that have been infected
humoral AND cell mediated immunity GOALAnswer: eliminate an identified antigen,
REMEMBER IT so that next time ADAPTIVE RESPONSES ARE FASTER
adaptive responses are a set ofAnswer: defenses that the body acquires as it responds to a
SPECIFIC ANTIGEN and LEARNS TO REMEMBER IT
primary exposureAnswer: few days to more than a week between detection and response
secondary exposureAnswer: same antigen is rapid and effective, frequently will not experience
disease symptoms while our bodies eliminate the pathogen

as foreign and worthy of attack
antigens recognized by (elements of adaptive immunity)Answer: 3 dimensional regions called
epitopes on antigens
antigens large foreign macromolecules (elements of adaptive immunity)Answer: make the
BEST antigens
antigens include various (elements of adaptive immunity)Answer: bacterial components and
proteins of viruses, fungi, and protozoa
food and dust can contain (elements of adaptive immunity)Answer: antigenic particles
