Final answer:
The right lymphatic duct drains the right side of the head, neck, thoracic cavity, and right arm, depositing lymph into the right subclavian vein.
Step-by-step explanation:
The right lymphatic duct is responsible for draining lymph fluid from the upper right side of the body, including the right side of the head, neck, thoracic cavity, and right arm. This duct empties into the right subclavian vein. While the right lymphatic duct handles the lymph drainage from these specific areas, the thoracic duct, which drains into the left subclavian vein, is responsible for draining a significantly larger portion of the body, including the lower limbs, left thorax, left upper limb, and the left side of the head.
