There are two primary lymphatic organs: the red bone marrow and the thymus gland. The development of white blood cells (haemopoesis) was covered briefly in the section on blood. Both T-cell and B-cells are 'born' in the bone marrow.
1 Thymus. 2  The thymus gland is the main organ of the lymphatic system. 3  Its primary function is to promote the development of specific cells of the immune system called T-lymphocytes. 4  Once mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen. The spleen is the largest organ of the lymphatic system. 2  Its primary function is to filter blood of damaged cells, cellular debris, and pathogens. 3  Like the thymus, the spleen houses and aids in the maturation of lymphocytes. 4  Lymphocytes destroy pathogens and dead cells in the blood.
