B and T Cells

Question 1

what activates T cells?

Answer 1

antigens presented on phagocyte

Question 2

Th Cells purpose

Answer 2

activate B and Tc cells

Question 3

Tc Cells purpose

Answer 3

killing pathogens (cellular the response)

Question 4

B cells

Answer 4

• each has their own specific antibody
• so the B cell with the complementary antibody will form an antigen-antibody complex
• so the right B cell is activated
• that B cell will then clone its self to form many plasma cells

Question 5

clonal selection

Answer 5

means that only the B cell which forms the antigen-antibody complex will divide so the response is specific

Question 6

plasma cells

Answer 6

clones of the B cell with the complementary antibody to the pathogenic antigen

Question 7

what do plasma cells do?

Answer 7

• make monoclonal antibodies -> forming A-A complex
• this sticks pathogens together (agglutination)
• so phagocytes can destroy many pathogens at once
• after the infection is over, plasma cells are saved as memory cellls
