This video illustrates normal lymphatic anatomy and flow. The lymphatic system plays a crucial role in immune function and in the delivery of vital nutrients to the body. Functioning almost like a sponge, the lymphatic system absorbs excess lymph fluid from the body’s organs and returns it to the blood stream. In a healthy body, the lymphatic channels from the liver and mesentery drain toward the thoracic duct, which is the main lymphatic vessel responsible for lymph drainage. In most people, the thoracic duct drains into the subclavian vein on the left side.
Normal Lymphatic Anatomy and Flow Video
Brittany Bennet, MA: The lymphatic system is a circulatory system with three main functions. First, it plays a key role in the immune system, which helps the body fight off infections and disease. Second, it is essential for transporting fatty acids, cells and large molecules. Third, the lymphatic system also collects excess fluid throughout the body and returns it to the veins.
This animation shows normal lymphatic anatomy and flow. Lymphatic fluid flows from the lower extremities -- the liver and intestine -- to the thoracic duct, which is the main channel for lymphatic drainage. In most people the thoracic duct drains into the subclavian vein on the left side.
