Question

multiple choice question
lymph from the right leg enters the bloodstream through the ______.
o lumbar trunk
o thoracic duct
o right lymphatic duct
o femoral trunk

Explanation:

The thoracic duct is the main lymph - collecting duct in the body. Lymph from the lower half of the body, including the right leg, enters the bloodstream through the thoracic duct. The right lymphatic duct drains lymph from the upper right quadrant of the body. The lumbar and femoral trunks are part of the lymph - collecting system but do not directly return lymph to the bloodstream; they feed into the thoracic duct.

Answer:

B. thoracic duct
