What area does the right lymph duct NOT drain from?

The right lymphatic duct is responsible for draining lymph from specific regions of the body, primarily those located in the right upper quadrant. It collects lymphatic fluid from the right side of the head, the right arm, and the right upper thorax. It does not drain the right leg. Instead, lymph from the legs, including the right leg, is drained by the thoracic duct, which serves a larger area of the body.

Understanding the anatomy and function of lymphatic drainage is crucial for identifying the correct answer. The distribution of lymphatic drainage leads to the realization that the right lymphatic duct has a more limited area of responsibility compared to the thoracic duct, which handles lymph from both lower limbs and the left side of the body. This distinction highlights that the right leg’s lymph vessels direct their flow toward the thoracic duct, thereby affirming that the right lymph duct does not drain this area.
