The External Iliac Artery is a major blood vessel that branches off from the Common Iliac Artery. It runs along the pelvic region and supplies blood to the lower limbs. This artery is crucial for delivering oxygenated blood to the legs and feet, supporting their function and health. As the External Iliac Artery continues downward, it becomes the Femoral Artery after passing under the inguinal ligament. This transition marks the artery's entry into the thigh, where it further branches into smaller arteries that nourish the muscles and tissues of the leg.
