Explanation:
Detailed explanation-1: -In primary immune responses, activated B cells differentiate into memory B cells, which are a key cellular component of the protective humoral responses to infectious pathogens. These cells develop within germinal centers of the secondary lymphoid organs.
Detailed explanation-2: -Once the immune response is complete, many of these cells die by apoptosis restoring the immune response to its original size-with one major change. Some of the B and T cells become memory cells, which are basically a pool of lymphocytes that are all set to combat the pathogen, if they encounter it again!
