Thoracic lymph duct
The thoracic duct is the largest lymphatic vessel within the human body, and plays a key role in the lymphatic system. A large portion of the body's lymph is collected by this duct and then drained into the bloodstream near the brachiocephalic vein between the internal jugular and the left subclavian veins.
Brachiocephalic vein: The brachiocephalic vein, is a vein that returns oxygen-depleted blood from the upper limbs, neck, and head to the heart.
