primary lymphoid organs - ANSWER organs in which lymphocyte precursors mature into antigenically committed , immunocompetent cells. In mammals, the bone marrow and thymus are the these organs in which B-cell and T-cell maturation occur, respectively. secondary lymphoid organs - ANSWER organs and tissues in which mature, immunocompetent lymphocytes encounter trapped antigens and are activated into effector cells. In mammals, the lymph nodes, spleen, and mucosal-associated lymphoid tissue (MA...
