The main collecting duct for the lymphatic system is the thoracic duct located alongside the aorta in the thoracic region of the body. Most lower body lymph (lymph from the fr â¦ ont and back of both legs and the abdominal area) migrate to the thoracic duct then from the duct, lymph dumps into the left subclavian vein.
