Primary lymphatic organs deliver lymphocytes and launch them into lymphatic vessels. The two Main lymphoid organs will be the thymus and pink bone marrow. Secondary lymphatic organs involve lymph nodes, tonsils, appendix and spleen. Lymph nodes are masses of lymphocyte made up of lymphoid tissues, attached to lymphoid vessels.
