What is Lymphedema? - Anatomy and Physiology of the Lymphatic System

The components of the Lymphatic system consist of lymphatic collectors, vessels and ducts, lymph nodes, peyer’s patches, tonsils, adenoids, spleen, thymus and the appendix. All of these have some impact on the lymphatic system, and the production of lymph fluid, which in itself may also be considered a part of lymphatic anatomy. Lymphatic collectors, vessels and ducts are responsible for the collection of lymph fluid into the vascular system that is responsible for transporting it back into the circulatory system.The lymph nodes process and filter lymph fluid. The spleen is responsible for filtering and storing blood and creating white blood cells. The Thymus is responsible for the maturation process of certain types of white blood cells. The tonsils and Adenoids are responsible for defense against harmful pathogens received through the oral and nasal passages. Peyer’s patches are responsible for eliminating harmful bacteria in the small intestine. And lastly, the appendix is responsible for mediating the destruction of bacteria in the intestine, though its full purpose is not believed to be completely understood at this time.
