The Common Iliac Artery is a major blood vessel that branches from the Abdominal Aorta. It is responsible for supplying oxygenated blood to the lower limbs and pelvic region. Each common iliac artery divides into two smaller arteries: the Internal Iliac Artery, which supplies blood to the pelvic organs, and the External Iliac Artery, which continues down to the leg. These arteries play a crucial role in the circulatory system, ensuring that vital organs and tissues in the lower body receive adequate blood flow. Understanding the anatomy and function of the common iliac artery is important in medical fields, especially in surgeries and treatments related to vascular health.
