Primary lymphatic drainage from the lower body enters the general circulation via which vein?

Explanation:
Lymph from the lower body returns to the bloodstream through the thoracic duct, which travels up to the neck and drains into the venous system at the left venous angle. That angle is formed by the junction of the left subclavian and left internal jugular veins, so the primary entry point for lymph from the lower body is the left subclavian vein. The right lymphatic duct handles the right upper quadrant, and the inferior vena cava is a venous channel, not where lymph empties.
