Answer 3

macrophage presents antigens on surface

Question 4

4-APC travels?

Answer 4

lymph node to activate specific T&B cells by clonal selection
cytokine and interleukin aids

Question 5

5- helper t cells

Answer 5

recognize antigen= activated so initiates clonal expansion

Question 6

6-activated helper t cells

release interleukin= stimulates activ of other immune cells eg neutrophils and B cells

Question 7

7- B cells activated

Answer 7

antib comp bind to antigen
interaction+ signal from helper t= plasma and memory
