Final answer:
The upper limb and lower body lymph drain into the right lymphatic duct and thoracic duct, respectively; the right duct drains into the right subclavian vein and the thoracic duct into the left subclavian vein.
Step-by-step explanation:
The upper limb and lower body lymphatics merge into larger lymphatic vessels and drain into different areas depending on their location in the body. The right lymphatic duct drains lymph fluid from the upper right side of the body into the right subclavian vein. Conversely, the thoracic duct is responsible for draining lymph from the lower limbs, the left thorax, the left upper limb, and the left side of the head into the left subclavian vein. The thoracic duct begins at the cisterna chyli and collects lymph from the lower abdomen, pelvis, and lower limbs through the lumbar trunks and the intestinal trunk before emptying into the bloodstream.
