Lymphoid tissue consists of many organs that play a role in the production and maturation of lymphocytes in the immune response. Lymphoid tissue may be primary or secondary depending upon its stage of lymphocyte development and maturation.

Lymphoid tissues are concentrations of lymphocytes and other immune cells within other organs of the body. The differentiation and development of B and T cells is critical to the adaptive immune response.

In this article we will discuss about the primary and secondary lymphoid organs. Primary Lymphoid Organs: In primary lymphoid organs, immature lymphocytes differentiate to mature ones into an antigen sensitive lymphocytes and after maturation, lymphocytes migrate to secondary lymphoid organs.

Lymphoid tissue is a ‘three-dimensional meshwork’ consisting of reticular fibers and fixed cells (macrophages and reticular cells) within which are lymphocytes, plasma cells, and granulocytes (Rose, 1981). From: Handbook of Vertebrate Immunology, 1998
