Definition
The femoral vein is a major blood vessel in the thigh that drains blood from the lower limb. It runs along the femur (thigh bone). It collects blood from smaller veins in the leg and foot. It carries deoxygenated blood back towards the heart. It becomes the external iliac vein as it enters the pelvis. The femoral vein plays a crucial role in the venous circulation of the lower body. It ensures blood returns efficiently from the leg.
