External Iliac Artery

The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and divides into two large branches - the inferior epigastric artery and a deep circumflex artery. These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the abdomen and becomes the femoral artery.
