STRUCTURE AND FUNCTION OF THE LYMPHATIC SYSTEM: Being a part of the circulatory system, lymphatic vessels link all the major organs to the main circulation. Apart from a network of conduits, the lymphatic system also connects various lymphoid tissues. Lymph nodes, spleen, liver and the bone marrow are all part of the lymphoid system. Together, these systems play a vital role in the body's defense mechanisms. (Martini & Bartholomew, 2010) Apart from participating in the body's immune system, the lymphatic system also plays a part in fluid balance and fat absorption from the gastrointestinal tract. As the blood and plasma circulate in the blood vessels, a large part of it leaks into the tissue. Lymphatic vessels hold the responsibility of carrying this fluid back to the main circulation. (Guyton & Hall, 2011) Another function of the lymphatic system is to aid absorption of lipids from the small intestine. The major end products of triglyceride digestion are 2-monoglycerides and fatty acids, which then diffuse as micelles into the brush border in the small intestine. In the mucosal cell, triglycerides are re-synthesized to form lipid droplets, known as chylomicrons. These leave the intestine in lymphatic vessels and enter the blood stream through the thoracic duct. (Guyton & Hall, 2011) STRUCTURE AND FUNCTIONS OF THE LYMPHATIC AND SKELETAL SYSTEM: The most complex relationship of the lymphatic system is with the lymphoid and skeletal system.
