The smallest vein in the body is called a venule.
Venules are tiny blood vessels that collect blood from capillaries and carry it to larger veins. They are the smallest part of the venous system, which is responsible for returning deoxygenated blood from the body to the heart.
While venules are the smallest veins, they are still larger than capillaries, which are the smallest blood vessels in the body.
Venules are crucial for transporting blood back to the heart, and they play a vital role in maintaining blood pressure and circulation.
