Lymph from the right arm and the right side of the head and thorax drains into the
A) thoracic duct.
B) vena cava.
C) right atrium.
D) right lymphatic duct.

Accepted Answer

The right lymphatic duct is responsible for draining lymph from the right arm and the right side of the head and thorax. The thoracic duct drains lymph from the left side of the body and is the largest lymphatic vessel in the body. The vena cava and right atrium are related to the cardiovascular system, not the lymphatic system.
