The dorsal venous arch of the foot is a superficial vein that connects the small saphenous vein and the great saphenous vein. Anatomically, it is defined by where the dorsal veins of the first and fifth digit, respectively, meet the great saphenous vein and small saphenous vein.

What does subclavian vein drain?
The primary function of the subclavian vein is to drain deoxygenated blood from the upper region of the body—including the arms and the shoulder areas—and transport it back to the heart. 6 Another important function of the subclavian is to collect lymph fluid from the lymphatic system from the internal jugular vein.
What is SF Junction?
The sapheno-femoral junction (SFJ) is located at the saphenous opening within the groin and formed by the meeting of the great saphenous vein (GSV), common femoral vein and the superficial inguinal veins (confluens venosus subinguinalis).
What do superficial veins do?
A superficial vein is close to your body’s surface and is often visible to the eye. Superficial veins may appear when lifting heavy weights or during a period of intense strength training. The superficial vessels are responsible for carrying the blood from the tissues closer to the skin’s surface to the deep veins.
How does venous drainage work?
The veins of the central nervous system drain deoxygenated blood from the cerebrum, cerebellum, brainstem and spinal cord. After emptying into the dural venous sinuses, most cerebral venous blood flows into the internal jugular veins before it is returned to the heart.
