The thoracic duct drains which portion of the body?

Explanation:
The thoracic duct handles the majority of lymph drainage in the body. It collects lymph from the left side of the head and neck, left upper limb, and essentially every structure below the diaphragm, and it drains into the venous system at the left venous angle (where the left internal jugular and left subclavian veins meet). The right lymphatic duct, not the thoracic duct, handles drainage from the right upper quadrant—the right side of the head and neck, right upper limb, and right side of the thorax. So the thoracic duct drains everything except the right upper quadrant.
