Pelvic circulation refers to the blood flow within the pelvic region, which is essential for delivering oxygen and nutrients to the organs and tissues located there. This circulation is primarily facilitated by the internal iliac arteries, which branch off from the common iliac arteries and supply blood to the pelvic organs, including the bladder, reproductive organs, and rectum. Veins in the pelvic area, such as the internal iliac veins, collect deoxygenated blood and return it to the heart. The pelvic circulation plays a crucial role in maintaining the health of the pelvic organs and supporting various bodily functions, including reproduction and waste elimination.
