Saphenous

Saphenous vein

The Saphenous vein is the longest vein within the human body, extending from the foot to the upper thigh and groin. It is part of the Peripheral vascular system and plays a crucial role in blood circulation.

Anatomy

The Saphenous vein is divided into two primary sections: the Great saphenous vein (GSV) and the Small saphenous vein (SSV). The GSV originates from the dorsal vein of the foot, while the SSV originates from the lateral marginal vein of the foot.

Function

The primary function of the Saphenous vein is to transport deoxygenated blood from the foot back to the heart. It also plays a significant role in thermoregulation, helping to cool the body during periods of high temperature.

Clinical significance

The Saphenous vein is often used in Coronary artery bypass surgery due to its length and accessibility. However, it is also prone to Varicose veins, a condition characterized by enlarged, twisted veins due to weak or damaged vein walls and valves.
