Chapter 17.2

Question 1

immunity brought about by protective molecules: antibodies

Answer 1

humoral immunity

Question 2

what are we producing antibodies for?

Answer 2

antigens

Question 3

where do B lymphocytes work in the humoral immunity?

Answer 3

extracellular space

Question 4

what happens in the extracellular space via B lymphocytes?

Answer 4

removes viruses, bacteria, and toxins by recognizing antigens and making specific antibodies

Question 5

where do B lymphocytes come from?

Answer 5

red bone marrow

Question 6

what secretes the antibodies?

Answer 6

plasma cells

Question 7

what types of antibodies are attached to B cell?

Answer 7

IgM or IgD

Question 8

responds to intracelular antigen

Answer 8

cell mediated immunity

Question 9

who works in cell mediated immunity?

Answer 9

T lymphocytes (T cells)

Question 10

What happens with T cells?

Answer 10

recognize antigenic peptide after macrophage processing

Question 11

chemical messengers that mediate interactions between cells

Answer 11

cytokines

Question 12

Definition: We need to activate B cells to produce plasma cells and memory cells

Answer 12

clonal expansion

Question 13

in mammalian cells that are a “self” marker

Answer 13

major histocompatability complex (MHC)

Question 14

you need an antigen presented with your MCH2 and show to the T helper cell

T helper cell then produces cytokines that activate the B cell

Answer 14

T-dependent antigens

Question 15

stimulate the B cell to make Abs

Answer 15

T-independent antigens

Question 16

B cell stimulated directly by antigen

Answer 16

T-independent cells

Question 17

Capsules of bacterial capsules

Answer 17

T-independent antigens

Question 18

first antibody when you have a T-independent antigen

Answer 18

IgM

Question 19

first antibody when you have a T-independent antigen

Answer 19

IgM

Question 20

reduces # of infectious units to be dealt with clumping

Answer 20

agglutination

Question 21

causes inflammation and cell lysis

Answer 21

activation of complement

Question 22

opsonization

Answer 22

coating antigen with antibody enhances phagocytosis

Question 23

blocks adhesion of bacteria and viruses to mucosa

Answer 23

neutralization

Question 24

target cell coated with antibodies; destroyed by immune cells that remain external to target cell

Answer 24

antibody-dependent cell-mediated cytotoxicity

Question 25

target cell coated with antibodies; destroyed by immune cells that remain external to target cell

Answer 25

antibody-dependent cell-mediated cytotoxicity

Question 26

activates cells related to cell-mediated immunity; macrophages, Tc cell, and natural killer cells

Answer 26

T Helper Cell

Question 27

Stimulated production of eosinophils, IgM and IgE

Answer 27

T helper Cell
