-lymph gland in the neck

Question 4

what type of immune response do b lymphocytes do?

Answer 4

-antibody mediated immunity

Question 5

what type of immune response do t lymphocytes do?

Answer 5

-cell medicated immunity

Question 6

what is antibody mediated immunity? what type of infections odes this respond to?

Answer 6

-antibodies that respond to antigens on body fluids e.g. blood and tissue fluid

Question 8

what is lymphocyte activation? is it a fast or slow process?

Answer 8

Question 9

Answer 10

-different

Question 11

how does lymphocyte activation occur in b lymphocytes?

Answer 11

-certain genes are activated to start a process that leads to the production of lymphocytes

Question 12

how does lymphocyte activation occur in t lymphocytes?

Answer 12

-a number of t cells are produced and cloned by mitosis and produce different t cells that fight against the infection
