11- immunity

Question 1

specific response includes

Answer 1

cellular response
humoral response

Question 2

cellular

Answer 2

T lymphs respond to antigens presented on body cells

Question 3

humoral

Answer 3

B lymphs where they produce antibodies in body fluids

Question 4

T helper

Answer 4

• receptors on CSM binding to complementary antigens on APCs
  produce interleukins(cytokine) stimulating B cells/phagocytes

(can form killer/memory)

Question 5

T-killer

Answer 5

kill foreign/abnormal cells by producing perforin
makes holes in CSM-> becomes freely permeable to water, causes cell death

Question 6

T memory

Answer 6

long term immunity

Question 7

humoral response

Answer 7

use of B lymphocytes producing antibodies

Question 8

B cells

Answer 8

have antibodies on CSM binding to complementary antigens
engulf antigens+APC
once activated(receptor binds), divide into plasma+memory

Question 9

plasma cells

Answer 9

B cells that produce+secrete antibodies against specific antigen
short lifespan of few days

Question 10

memory cells

Answer 10

B cell providing long term immunity against specific pathogen- longer lifespan
rapidly divide into plasma cells if body re-infected by same pathogen

Question 11

helper T cells

Answer 11

bind to APC to activate division of B cells

Question 12

Clonal SELECTION

Answer 12

B cell with the correct antibody is selected for cloning (by being activated by a T helper cell)

Question 13

Clonal EXPANSION

Answer 13

DIVISION of specific B cells to produce genetically identical clones
