Transcript text: The right lymphatic duct receives lymph from the:right leg.left leg.left arm.right arm.
Solution
The answer is the fourth one: right arm.
Explanation for each option:
Right leg: Incorrect. The right lymphatic duct does not receive lymph from the right leg. The lymph from both legs drains into the thoracic duct, which is the larger of the two main lymphatic ducts.
Left leg: Incorrect. Similar to the right leg, the lymph from the left leg also drains into the thoracic duct.
Left arm: Incorrect. The lymph from the left arm drains into the thoracic duct, not the right lymphatic duct.
Right arm: Correct. The right lymphatic duct receives lymph from the right arm, as well as the right side of the head and neck, and the right side of the thorax.
In summary, the right lymphatic duct specifically drains lymph from the right arm, along with other regions on the right side of the upper body.
