Pelvic blood vessels are crucial components of the circulatory system located in the pelvic region. They include arteries and veins that supply blood to the organs and tissues in the pelvis, such as the bladder, reproductive organs, and rectum. The primary artery in this area is the internal iliac artery, which branches off from the common iliac artery. Veins in the pelvic region, including the internal iliac vein, help return deoxygenated blood to the heart. These vessels play a vital role in maintaining proper blood flow and supporting the functions of the pelvic organs. Understanding pelvic blood vessels is important for diagnosing and treating various medical conditions.
