Quizplus · Accepted Answer

The thoracic duct is the largest lymphatic vessel in the body and drains lymph from about three fourths of the body, including the left upper limb, left side of the thorax, left side of the head and neck, and the entire lower half of the body. It then empties into the left subclavian vein. The right lymphatic duct drains lymph from the right side of the head, neck, and thorax, and empties into the right subclavian vein. The cisterna chyli is a dilated sac at the lower end of the thoracic duct where lymph from the intestinal trunk and the two lumbar lymphatic trunks is received. The spleen filters blood, not lymph.
