The bone marrow and thymus are primary lymphoid tissues and the sites of lymphocyte development. The lymph nodes, spleen, tonsils and Peyer’s patches are examples of secondary lymphoid tissue.Why are lymph nodes considered secondary lymphoid tissue?Secondary lymphoid tissues are sites where lymphocytes interact with each other and nonlymphoid cells to generate immune responses to antigens. These include the spleen, lymph nodes, and mucosa-associated lymphoid tissues (MALT).
