Question

Quizplus · Accepted Answer

Memory cells are a type of lymphocyte, either B or T cells, that are created during the primary immune response to a pathogen. These cells are capable of remembering the specific pathogen and mounting a faster, more effective secondary response if the same pathogen is encountered again in the future. Memory cells can remain in the body for many years after the initial exposure to the pathogen.
