• Veins
The veins are subdivided into three systems. The deep or epifascial system returns approximately 85 percent of the blood and the superficial or intermuscular system approximately 15 percent. A series of venous valves called the perforating system interconnects the superficial and deep systems. In the standing posture, the veins of the leg have to handle an exceptional load as they act against gravity when they return the blood to the heart. The venous valves assist in maintaining the superficial-to-deep direction of the blood flow.
