Accepted Answer

The lymph ducts in the thoracic cavity, specifically the thoracic duct (the main duct for lymph drainage) and the right lymphatic duct, drain into the venous system at the junction of the internal jugular vein and the subclavian vein. This allows the lymph, which includes proteins, lipids, and other substances, to re-enter the bloodstream.
