The lymphatic system is essential in maintaining the fluid homeostasis and optimal functioning of the immune system. Unlike the circulation of blood in the vascular system, lymphatic flow occurs through a low-pressure system. The interstitial fluid enters the distal lymphatics which coalesce into conduits of increasing caliber, ultimately draining lymph into the systemic circulation through the thoracic duct.
