Question

Quizplus · Accepted Answer

Most lymphatic vessels drain into the thoracic duct, which is the largest lymphatic vessel in the body. It drains lymph from the lower limbs, abdomen, left chest, left arm, and left side of the head, neck and thorax, and 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. However, it only receives lymph from the upper right side of the body, while the thoracic duct receives lymph from the rest of the body. The inferior vena cava and pulmonary veins do not receive lymphatic drainage.
