Lymphatic tissue is rich in lymphocytes (and accessory cells such as macrophages and reticular cells). The lymphatic tissue includes the lymph nodes, spleen, tonsils, adenoids and the thymus (an organ in the chest that is particularly large during infancy). In medicine, a tissue is a broad term that is applied to any group of cells that perform specific functions. A tissue in medicine need not form a layer.
The lymphatic system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells, or leukocytes). Lymphatic vessels branch, like blood vessels, into all the tissues of the body. The lymphatic system has three main functions. First, it returns excess interstitial fluid (also called tissue fluid) to the blood. Of the fluid that leaves the capillaries, about 90 percent is returned. The 10 percent that doesn't return becomes part of the tissue fluid that surrounds the tissue cells.
