The lymphatic trunk trains the lymph fluid into two lymph ducts: The thoracic lymph duct and the right lymphatic duct.
The thoracic lymph duct takes the lymph from the lower left halves of the body. It is the largest lymph vessel. It carries the lymph and chyle (emulsified fatty acids) back into the bloodstream. It drains lymph into the circulatory system via the left brachiocephalic vein.
