Primary and secondary lymphoid organs

Primary lymphatic organs are where lymphocytes are formed and mature. They provide an environment for stem cells to divide and mature into B- and T- cells: There are two primary lymphatic organs: the red bone marrow and the thymus gland.

Secondary lymphoid organs (SLOs) include lymph nodes (LNs), spleen, Peyer's patches (PPs) and mucosal tissues- the nasal associated lymphoid tissue (NALT), adenoids, and tonsils.
