Saphenous Vein

The Saphenous Vein (/səˈfiːnəs veɪn/) is the largest vein in the human body, extending from the foot to the upper thigh and groin.

Etymology

The term "saphenous" is derived from the Greek word "saphēnós," meaning "clearly visible." This is in reference to the vein's prominent visibility in the legs.

Anatomy

The Saphenous Vein is divided into two primary sections: the Great Saphenous Vein (GSV) and the Small Saphenous Vein (SSV). The GSV is the longest vein in the body, running along the length of the lower limb, while the SSV runs along the back of the calf muscle.

Function

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