उत्तर
Secondary lymphoid organs known as mucosa-associated lymphoid tissue (MALT) are located near the epithelial linings of many important systems, such as the respiratory, digestive, and urogenital tracts. Nearly half of the body's lymphoid tissue is made up of MALT, which enables lymphocytes to engage with antigens. It is the location where lymphocyte proliferation and differentiation occur. To interact with the antigens in these organs, mature lymphocytes travel there, where they multiply to form effector cells.
