Test 1 chapter 8

Question 1

rapid
nonspecific
short-lived

Answer 1

inflammatory response

Question 2

slower
specific
long-lived memory

Answer 2

adaptive immune response

Question 3

substances capable pf generating an immune response

“non self”

Answer 3

antigens

Question 4

associated with the body fluids and due to the production of soluble proteins call antibodies

Answer 4

humoral immunity

Question 5

associated with the development of “trained” armies of the T lymphocytes

Answer 5

cellular immunity

Question 6

antibodies circulate in the blood and binds to antigens on infectious agents. this can result in direct or indirect response

Answer 6

humoral immunity

Question 7

inactivates microorganism

Answer 7

direct response

Question 8

activates inflammatory mediators that destroy pathogen

Answer 8

indirect

Question 9

antibodies are responsible for protection against what

Answer 9

many bacteria and viruses

Question 10

T cell differentiation which lead to direct, indirect or avoid attacking self

Answer 10

cellular immunity

Question 11

cell mediated immunity protects against what

Answer 11

viruses and cancer

Question 12

lymphocytes that downgrade the immune response and also provide tolerance to self

Answer 12

T regulatory cells

Question 13

lymphocytes that are trained killer cells, they destroy host cells infected by bacteria/viruses and cancer cells

Answer 13

Cytotoxic T cells

Question 14

have perviously encountered and responded to their antigen

Answer 14

memory T cells

Question 15

react with antibodies/antigen receptors on B and T cells to induce immune response

Answer 15

antigens

Question 16

Immunogenicity

Answer 16

Foreignness
Molecular size
chemical complexity
sufficient quantity

Question 17

Most abundant antibody
Can cross capillary walls to enter or exit tissue
Can cross the placenta giving the newborn immediate protection to all the disease and vaccinations the moth has ever had

Answer 17

IgG

Question 18

made after IgM and IgG against same antigen

found in mucus membranes

Answer 18

IgA

Question 19

largest and most effective antibody
made first in response to infection
blood types

Answer 19

IgM

Question 20

mediates parasitic and allergic response

Answer 20

IgE

Question 21

located on the surface of B lymphocyte memory cells

Answer 21

IgD

Question 22

antigens require processing and presentation by what

Answer 22

antigen presenting cells APC

Question 23

APC activates what

Answer 23

T helper cells

Question 24

For processing and presentation…

Answer 24

Antigen must be appropriate type
Lymphocytes must be prepared to recognize presented antigen
Antigen must be presented appropriately

Question 25

help antigen-driven maturation of B and T cells

Facilitate and magnify interaction between APCs and immunocompetent lymphocytes

Answer 25

Helper T cells

Question 26

step of helper T cells

Answer 26

TH interacts through antigen-specific and antigen independent mechanisms
Undergoes differentiation
Mature Th interacts with plasma or T effector cells

Question 27

provide help in developing cell-immdiated immunity

Answer 27

TH1 cell subsets

Question 28

provide help in developing humoral immunity

Answer 28

TH2 cell substrates

Question 29

Latent period after novel antigen exposure
After 5-7 days IgM antibody detected
IgG response but more IgM

Answer 29

primary response

Question 30

more rapid with larger antibody amounts
Presence of memory cells, differentiation not required
IgG produced in greater amounts

Answer 30

secondary response

Question 31

adaptive immunity can be either

Answer 31

passive or active

Question 32

antibodies or T cells produced after either natural exposure to antigen or immunization
Long-lived

Answer 32

Active immunity

Question 33

Preformed antibodies or T lymphocytes are transferred from donor to recipient Ex. placenta
Short-lived

Answer 33

passive immunity
