immune system,

n a biochemical complex that protects the body against pathogenic organisms and other foreign bodies. It incorporates the humoral immune response, which produces antibodies to react with specific antigents, and the cell-mediated response, which uses T cells to mobilize tissue macrophages in the presence of a foreign body. It also protects the body from invasion by creating local barriers and inflammation. The principal organs include the bone marrow, the thymus, and the lymphoid tissues.

immune system, duality of,

n the division of lymphocyte white blood cells into two classes of cells, types B and T. Type B cells help develop humoral immunities, while type T cells are active in cellular immunity.
