Answer 1

Lymph from the right leg re-enters the circulation through the thoracic duct, which drains into the left subclavian vein.

Step-by-step explanation:

The lymph collected from the right leg is introduced back into circulation through the thoracic duct. This duct originates at the cisterna chyli, a sac-like chamber located just beneath the diaphragm, which receives lymph from the lower abdomen, pelvis, and lower limbs via the left and right lumbar trunks and the intestinal trunk.

As lymph from the right leg travels through the lymphatic vessel network, it bypasses the right lymphatic duct, which only drains the upper right quadrant of the body. Instead, it enters the larger thoracic duct, eventually draining into the left subclavian vein, where it rejoins the venous bloodstream.
