Where does lymph from the right upper extremity and right side of the head drain?

Thoracic duct
Right lymphatic duct
Left subclavian vein
Aorta

The correct answer is: Right lymphatic duct

Lymph from the right upper extremity and the right side of the head drains into the right lymphatic duct. This structure is responsible for collecting lymph from specific regions of the body, including the right arm, right side of the head, neck, and right thorax. It then empties this lymph into the right subclavian vein, facilitating the return of lymph to the bloodstream. The thoracic duct, while it plays a significant role in draining lymph from the rest of the body (particularly the left side and lower parts), does not receive lymph from the right upper extremity or the right side of the head. The left subclavian vein is also irrelevant here, as it pertains solely to the lymphatic drainage from the left side of the body. The aorta, being a major artery, is not involved in the lymphatic system's drainage process at all. Thus, the right lymphatic duct is the correct structure involved in this specific drainage pathway.
