Primary And Secondary Immune Response

Question 1

What is the primary immune response?

Answer 1

-Slight delay due to antigen presentation, selection of complimentary T and B cells, and mitosis
-Cloned plasma cells produce antibody molecules
-Customer cells die off and antibody concentration declines
-Memory cells remain in circulation and stored in lymph nodes

Question 2

It’s a secondary immune response?

Answer 2

-Rapid increase in antibody concentration due to immediate activation of memory T and B cells
-Many cloned plasma cells produce very large quantities of antibody molecules in a short period of time
-Plasma cells die off antibody concentration declines
-Memory cells remain in circulation and stored in lymph nodes

Question 3

What is antigen variability?

Answer 3

-Gene mutation changes the antigens on the surface of a pathogen
-Antigens are no longer complimentary to the surface receptors of memory cells so no secondary response

Question 4

What is a natural response

Answer 4

Become immune after catching the disease

Question 5

What is an artificial response

Answer 5

Become immune after a vaccination

Question 6

Active natural immunity

Answer 6

-individual becoming infected with disease
-body produced its own antibodies
-plasma cells produce the antibodies
-B memory cells are formed
-Long lasting

Question 7

Active artificial immunity

Answer 7

-vaccination
-memory cells are formed
-long lasting

Question 8

Passive natural immunity

Answer 8

-baby becomes immune due to the antibodies received from mother through placenta or breast milk
-short lived
-no memory cells

Question 9

Passive artificial immunity

Answer 9

-become immune after being injected with antibodies from someone else
-short lived
-no memory cells
