The Internal Iliac Artery is a major blood vessel that branches off from the Common Iliac Artery. It supplies blood to the pelvic region, including the pelvic organs, gluteal region, and part of the thigh. This artery is crucial for delivering oxygenated blood to various structures, such as the bladder, rectum, and reproductive organs. The Internal Iliac Artery has several branches, including the Superior Gluteal Artery and the Inferior Gluteal Artery, which further supply blood to the muscles and skin of the buttocks. Understanding its anatomy is important in medical fields, especially in surgeries involving the pelvis and lower limbs.
