Common iliac artery
The common iliac artery originates from the abdominal aorta. The aorta is the main trunk of the systemic arteries in the cardiovascular system. This system carries oxygenated blood from the heart to the other areas of the body and back. At the fourth lower lumbar vertebral body the aorta ends by dividing into the right and left common iliac arteries. The two arteries travel below and to one side for about four to five centimeters towards the edge of the pelvis. It splits into an internal and external iliac artery at the level of the pelvic inlet. The internal iliac artery supplies the pelvic organs including the urinary bladder, the man's prostate gland, and the woman's uterus and vagina. The external iliac artery through - the femoral artery supplies the thigh - the popliteal artery supplies the knee area and the anterior and posterior tibial arteries supply the area below the knee including the feet and toes. The common iliac artery is a paired structure, meaning there is one on the right and one on the left of the body.
