The lymphatic system in vertebrates is a network of conduits that carry a clear fluid called lymph. It also includes the lymphoid tissue through which the lymph travels. Lymphoid tissue is found in many organs, particularly the lymph nodes, and in the
lymphoid follicles associated with the digestive system such as the tonsils. The system also includes all the structures dedicated to the circulation and production of lymphocytes, which includes the spleen, thymus, bone marrow and the lymphoid tissue associated with the digestive system. The lymphatic system as we know it today was first described independently by Olaus Rudbeck and Thomas Bartholin. However, Hippocrates was the first person to mention the lymphatic system in fifth century BC. Rufus of Ephesus, a Roman physician, identified the axillary, inguinal and mesenteric lymph nodes as well as the thymus during the first to second century AD
The dissolved constituents of the blood do not directly come in contact with the cells and tissues in the body, but first enter the interstitial fluid, and then the cells of the body. Lymph is the clear, protein rich fluid that is formed when interstitial fluid enters the conduits of the lymphatic system. The lymph is not pumped through the body like blood, but is moved mostly by the contractions of skeletal muscles.
The lymphatic system has three interrelated functions.
1) It is responsible for the removal of interstitial fluid from tissues.
2) It absorbs and transports fatty acids and fats as chyle to the circulatory system.
3) The transport of antigen presenting cells (APCs), such as dendritic cells, to the lymph nodes where an immune response is stimulated.
The study of lymphatic drainage of various organs is important in diagnosis, prognosis, and treatment of cancer. The lymphatic system, because of its physical proximity to many tissues of the body, is responsible for carrying cancerous cells between the various parts of the body in a process called metastasis. The intervening lymph nodes can trap the cancer cells. If they are not successful in destroying the cancer cells the nodes may become sites of secondary tumors.
Diseases and other problems of the lymphatic system can cause swelling and other symptoms. Problems with the system can impair the body’s ability to fight infections.
In the early 1930’s, Danish physiotherapists Emil and Astid Vodder developed their system of Manual Lymphatic Drainage, which has become the basis for most Lymphatic Drainage massage techniques used today. In the 1970’s, Hungarian physicians Michael & Ethel Foldi combined Vodder’s MLD with a variety of other massage, exercise and hydrotherapies into a comprehensive treatment for Lymphedema. This is called Complete Decongestive Therapy.
