Transcript text: The duct that drains lymph from the body below the diaphragm, the left upper limb and the left side of the head neck and thorax is the $\qquad$
right lymphatic duct
bronchomediastinal trunk
thoracic duct
Solution
The answer is the third one: thoracic duct.
Explanation for each option:
Right lymphatic duct: This duct drains lymph from the right upper limb, right side of the head and neck, and the right side of the thorax. It does not drain lymph from below the diaphragm or the left side of the body.
Bronchomediastinal trunk: This is a major lymphatic vessel that drains lymph from the thoracic viscera and the thoracic wall, but it does not cover the extensive areas mentioned in the question.
Thoracic duct: This is the correct answer. The thoracic duct is the largest lymphatic vessel in the body and drains lymph from the entire body below the diaphragm, the left upper limb, and the left side of the head, neck, and thorax.
In summary, the thoracic duct is responsible for draining lymph from the specified regions in the question.
