Question

Quizplus · Accepted Answer

Memory cells are generated during the primary immune response and enable the immune system to launch a faster, stronger response to a previously encountered antigen during a secondary immune response. Memory cells "remember" the antigen and can quickly produce large numbers of specific antibodies and T cells in response to a subsequent encounter with the same antigen. The other choices - plasma cells, helper T cells, NK cells, and pathogenic cells - do not play a direct role in generating memory responses.
