What is "dorsal venous arch"?

The dorsal venous arch is a network of veins located on the top surface of the foot. It is formed by the union of smaller veins from the toes and connects to the larger veins of the lower leg. The dorsal venous arch serves as a drainage system for deoxygenated blood from the foot, allowing it to return to the heart for oxygenation. It plays an important role in maintaining circulation and venous return in the lower extremities.
