UNIVERSIDAD DE ZAMBOANGA HIGH SCHOOL DEPARTMENT JS Alano St. Zamboanga City, Zamboanga City Anatomy and Physiology LYMPHATIC SYSTEM Introduction The lymphatic system transports a fluid called lymph through lymphatic capillaries and vessels called lymphatics. The system controls body fluids and destroys harmful microorganisms. The system consists of lymph, lymph vessels, lymph nodes, the tonsils, the spleen, the thymus gland and Peyer’s patches in the intestine. The Functions of the System and functions of the Lymphatic vessels The functions of the system are to drain interstitial fluid from tissues spaces, to transport fats from the digestive tract to the blood, to develop immunities and to produce lymphocytes. Some blood plasma gets forced through the blood capillary walls into spaces between tissue cells. This is called interstitial fluid. Lymphatic capillaries drain intestinal fluid, which is now called lymph, and pass this fluid on to lymph vessels called lymphatics. In the villi of the small intestine, special lymphatics called lacteals pick up fats and transport them to the blood. Lymph in lacteals looks milky due to the fats and is called chyle. Lymphatic Vessels Lymphatic vessels originates singly or in plexuses as blind- end tubes called lymphatic capillaries between cells in most part of the body. Lymphatic capillaries unite to form larger vessels called lymphatics, which resemble veins but are thinner and have more valves. Valves ensure a one-way flow of lymph. Eventually, all lymphatics converge into two main channels: the thoracic duct and the right lymphatic duct.
