4

Question 23

must be highly specific to an antigen on a pathogen

Answer 23

specificity

Question 24

microbe parts to specificity that provoke an immune response

Answer 24

antigens

Question 25

any molecule that our body recognizes as nonself

Answer 25

antigen

Question 26

the immune system recognizes unique _________ that then combine with immune cells or antibodies

Answer 26

epitopes

Question 27

regions on the antigen that get picked up by the pathogen

Answer 27

epitopes

Question 28

this process in adaptive immunity detects what is self and what is a threat

Answer 28

tolerance of self

Question 29

these prevent other T cells from attacking self cells through immune suppression

this is the ability to remember past pathogen exposures

Answer 32

immunological memory

Answer 34

during minimal self damage

Answer 36

humoral immunity

Question 37

what are the two steps to humoral immunity

Answer 37

activation of B cells and production of antibodies against the antigen
