T killer cell

Answer 2

destroy pathogen carrying antigens.

produce chemical called perferin, kill pathogen by making holes in membrane

Question 3

t memory cell?

Answer 3

immunological memory

divide rapidly to form clones of the killer cells that kill recognised pathogen

Question 4

Answer 4

stop immune response after pathogen is killed.

recognise self antigens and stops auto immune response
