The thoracic duct and right lymphatic duct are the two collecting ducts that drain the lymphatic vessels. The thoracic duct receives lymphatic drainage from the left side of the head, neck, chest, abdomen, and left arm, while the right lymphatic duct receives lymphatic drainage from the right side of the head and neck, right arm, and right thorax. Both ducts empty their lymphatic contents into the subclavian veins. None of the other choices include the correct ducts or vessels that drain lymphatic fluid.
