immunity

Question 1

Define immunity

Answer 1

the body to resist a particular infection or toxin by the action of a specific antibodies or sensitized white blood cells.

Question 2

What does the body non specific respond to

Answer 2

Respond to a range of pathogens or foreign substances

Question 3

What does the body adaptive respond to

Answer 3

respond to a particular pathogen or foreign substance

Question 4

What is autoimmune disease

Answer 4

when the body natural defence can’t tell the difference between own cells and foreign cells.

Question 5

What is a hypersensitivity reaction

Answer 5

immunological response occurs in response to an antigen or allergen

Question 6

The ability of our immune cells to recognise and not attack our own body cells is known as
a) self tolerance
b) memory
c) immunocompetence
d) specificity

Answer 6

a

Question 7

What is the first line of defence in non specific resistance include:
a) antimicrobial proteins and natural killers
b) Inflammation and fever
c) Skin secretion and mucous membrane
d) Humoral and cellular immunity

Answer 7

c

Question 8

What is the second line of defence in non specific:
a) skin secretion
b) antimicrobial proteins and natural killers
c) Humoral and cellular immunity

Answer 8

b

Question 9

Humoral immunity have two response what are they

Answer 9

active
Passive

Question 10

How is active immunity naturally acquired

Answer 10

infection
contact with pathogen

Question 11

How is active imunity artificially acquired

Answer 11

vaccine from dead or attenuated pathogens

Question 12

How is passive immunity naturally acquired

Answer 12

antibodies pass from mother to foetus via placenta or infant in her milk

Question 13

How is passive immunity artificially acquired

Answer 13

Injections of immune serum

Question 14

What is a autoimmune response

Answer 14

When the body fails to to recognise self from non self the immune system will attack its own tissue.

Question 15

example of an autoimmune disease

Answer 15

rheumatoid arthritis

Question 16

Name the two types of immunity that’s is adaptive and what cells they use

Answer 16

humoral immunity- B cells
Cellular immunity - t cells

Question 17

what are immunocompetence

Answer 17

ability to be able to detect the difference between the different pathogens.

Question 18

where are lymphocytes developed

Answer 18

red bone marrow

Question 19

what happen when the B cells are stimulated by the antigen

Answer 19

they clone and become plasma cells that produce antibodies

Question 20

TRUE or FALSE

Answer 21

TRUE

Question 22

a) self tolerance
b) memory
c) immunocompetence
d) specificity

Answer 22

c

Question 23

where are lymphocytes created

Answer 23

red bone marrow

Question 24

Three ways the adaptive immunity is characterised

Answer 24

specificity
immunological memory
self and non self recognition

Question 25

where does T cells develop immunocompetence

Answer 25

thymus

Question 26

Where does B cells develop immunocompetence

Answer 26

in red bone marrow

Question 27

When a B cell detect an antigen what happens to the B cell what is produced

Answer 27

B cells clone and produce plasma cell

Question 28

What does plasma cells produce

Answer 28

Antibodies

Question 29

What response is T cells involved in

Answer 29

Cell mediated

Question 30

What does memory cells do

Answer 30

the second response to much quicker

Question 31

What are the two type of T cells are there

Answer 31

Killer
Helper

Question 32

What T cell is this
Directly attack the invading antigen

Answer 32

Killer T cells

Question 33

What T cell is this
Help both antibody mediated and cell mediated responses

Answer 33

Helper T cells

Question 34

what is hypersensitivity

Answer 34

occurs when a person reacts to a substance normally tolerated by most other people
