The right iliac artery is a major blood vessel that branches from the abdominal aorta. It supplies oxygenated blood to the right side of the pelvis and lower limb. This artery is part of the systemic circulation and plays a crucial role in delivering nutrients and oxygen to the tissues in its region. As it descends, the right iliac artery divides into two main branches: the right internal iliac artery and the right external iliac artery. The internal branch supplies blood to the pelvic organs, while the external branch continues down to become the femoral artery, which supplies the thigh and leg.
