immune system

Question 1

natural killer cell

Answer 1

cell w cytotoxic granules
cause apoptosis to cells

Question 2

innate immunity

Answer 2

doesn’t differentiate
present at birth

Question 3

phagocytic cells

Answer 3

macrophages
dendritic cells
monocytes
mast cells
eosinophils

Question 4

histamine

Answer 4

compound released in response to injury and allergy
cause vasodilation so cells can pass through and move to site of injury, and promote swelling

Question 5

pyrogens

Answer 5

promote fever and destroy pathogens

Question 6

b cells

Answer 6

produce antibodies

Question 7

dendritic cell

Answer 7

antigen-presenting
link innate and adaptive
in mucous membranes
phagocytosis

Question 8

adaptive immunity

Answer 8

pathogen specific
rely on self recognition

Question 9

primary response

Answer 9

symptom of first infection
relatively severe bc take time for initial adaptive resp

Question 10

secondary response

Answer 10

re-exposure to same pathogen
based on immunological memory

Question 11

helper t cell

Answer 11

secrete cytokines that enhance other responses
has CD4 molecule

Question 12

cytotoxic t cell

Answer 12

kill target cells w apoptosis
has CD8 molecule

Question 13

IgG

Answer 13

largest amount
attack virus and antibodes

Question 14

IgE

Answer 14

funct in allergic reactions
release histamine

Question 15

IgD

Answer 15

bind surface B cells and help active them

Question 16

IgM

Answer 16

w IgG form immune complexes

Question 17

IgA

Answer 17

in secretion and attack pathogen

Question 18

naturally acquire immunity

Answer 18

natural exposure trigger immune response

Question 19

artificially acquired immunity

Answer 19

non natural exposure trigger immunity
ex. vaccine

Question 20

artificially acquired passive immunity

Answer 20

give antibodies

Question 21

naturally acquired passive immunity

Answer 21

given antigens

Question 22

allergies

Answer 22

b cells over produce IgE

Question 23

lymph nodes

Answer 23

structure remove debris and pathogen fr lymph
has outer cortex and inner medulla
opening = sinuses
has macrophages and lympcytes

Question 24

lymphatic system

Answer 24

capillaries get interstitial fluid left fr circulatory
filter fluid and put it back
transport fats

Question 25

lymphatic capillaires

Answer 25

not in cns, bone marrow, anywhere w less blood flow
flow one direction w valves = up permeability

Question 26

lymphatic vessels

Answer 26

one way flow w vessles
collection of capillaries
smooth muscle contraction push fluid
