👉 The appendix veins are small blood vessels that drain the appendix, a small, tube-like organ attached to the large intestine. These veins carry deoxygenated blood and waste products from the appendix back to the circulatory system. The main veins of the appendix, called the appendiceal veins, join together to form the mesenteric vein, which then drains into the portal vein in the liver. Although their exact function is still debated, it is believed that the appendix veins play a role in immune function and waste removal.
