Question 6

Macrophage to Helper T (Cell mediated)

Answer 8

keeps in memory which cells to kill next time

Question 9

stops immmune response (tells killer cells to stop fighting so they don’t kill the good cells also)

Question 10

Macrophage to helper T (humoral)

Answer 10

can’t decide whether the antigen is good or bad - sends to B cell

Question 11

B cell

Answer 11

decides whether antigen is good or bad

Question 12

Memory B

Answer 12

keeps in memory which cells to kill next time - make more antibodies

Question 13

Plasma cell

Answer 13

makes antibodies that wrap around bad cells

Question 14

suppressor B

Answer 14

stops the antibodies

Question 15

the main difference between humoral and cell mediated

Answer 15

Question 24

which increases WBC production

Answer 24

filgrastin (neupogen)

Question 25

why are transplant patients more susceptible to infection

Answer 25

they are on immuno-suppressants so the organ doesn’t get rejected - so their immune system is weakened
