Definition
Rectal veins are blood vessels that drain blood from the rectum. They play a key role in returning deoxygenated blood from the rectum to the heart. Think of them as the plumbing system for your lower digestive tract. These veins connect to larger veins, eventually reaching the inferior vena cava. They help maintain healthy blood circulation in the pelvic region. They're essential for proper bowel function and overall health. Problems with these veins can lead to hemorrhoids.
