saphenous vein

The saphenous vein is a large superficial vein in the leg that runs from the foot up to the groin. It plays a key role in returning blood back to the heart from the lower limbs. Because of its size and accessibility, it’s often used in medical procedures like bypass surgery for blocked arteries. The vein's proximity to the surface makes it easy for surgeons to access, and it generally has good blood flow, making it a reliable vein for transplant or other treatments.
