MICROANATOMY

Detailed explanation-1: -Adaptive immune responses depend on the ability to recognize and eliminate recurrent pathogens, resulting in the generation of memory lymphocytes. The capacity of memory T cells to rapidly mobilize and initiate a potent recall response enhances protective immunity against previously encountered pathogens.

Detailed explanation-2: -Because our memory cells are “experienced, ‘’ we will respond to a second (or subsequent) encounter more quickly. Whereas in a primary encounter, antibodies are not generated for several days, during a memory response antibodies appear in just a few days.

Detailed explanation-3: -Memory B and T-cells are antigen-specific and, on encountering the antigen again, can mount a more rapid and effective immune response, known as the secondary immune response.
