Explanation:
Detailed explanation-1: -T-cell memory generated after the first antigen encounter can last for decades, and provides long-lasting immune protection (1, 2). It has convincingly been shown that T-cells with a memory phenotype in human blood renew quite often and are not maintained by a long cellular lifespan (3–11).
Detailed explanation-2: -After the T and B lymphocytes have matured in the thymus and bone marrow, they then travel to the lymph nodes and spleen where they remain until the immune system is activated. Lymph nodes are located throughout the body.
