Lymphoid - "tissue in which lymphocytes are produced, consisting of aggregations of lymphocytes either as discrete organs such as tonsils and lymph nodes, or as diffuse aggregations in connective tissue. Primary lymphoid organs are the bone marrow and thymus in which lymphocyes are produced which then migrate to the secondary lymphoid tissues (e.g. lymph nodes, spleen) where they mature, encounter foreign antigens, and participate in immune reactions."
