Answer 2

spleen, tonsil, lymph vessel, adenoids, skin, and liver

Question 3

what are leukocytes

Answer 3

white blood cells that defend against foreign material

phagocytes, mast cells, eosinophils, basophils and natural killer cells

Question 5

what is the most abundant phagocyte

Answer 5

neutrophils

Question 6

the two types of lymphocytes of adaptive response

Answer 6

B cells and T cells

Question 7

where do B cell mature

Answer 7

in the bone marrow

Question 8

where do T cells mature

Answer 8

in thymus

Question 9

what cells are seen in humoral response

Answer 9

B lymphocytes

Question 10

what cells are seen in cell mediated response

Answer 10

T lymphocytes

Question 11

what is an antigen

Answer 11

protein that binds to specific antibody

Question 12

what is an antibody

Answer 12

protein made by B lymphocyte that binds to antigen

Question 13

B cells have ___________ on surface

Answer 13

membrane bound antibodies

Question 14

how does B cell become activated

Answer 14

when pathogen binds to antibodies

Question 15

what do B memory cells do

Answer 15

will proliferate in response to pathogen

Question 16

what do effector B cells do

Answer 16

they produce antibodies

Question 17

what is opsonization

Answer 17

when pathogen is tagged so phagocytes can eliminate

Question 18

what happens if pathogen attaches to antibody on B cell

Answer 18

B cell will engulf and break pathogen and attach it to MCH II and present antigen

Question 19

what is function of effector T helper cells

Answer 19

raises alarm and releases cytokines

Question 20

what are cytokines

Answer 20

chemical alarm for cells

Question 21

function of MHC I complex

Answer 21

bind to shady things inside of cells and present to membrane

Question 22

function of effector cytotoxic T cells

Answer 22

will bind to things that present same antigen on MHC I complex

Question 23

what occurs when effector Tc cells bind to MHC I complex

Answer 23

will release perforins or grazymes

Question 24

what does perforins do

Answer 24

causes gaps/holes on membrane

Question 25

granzymes do what

Answer 25

cause cells to kill itself
