The only veins that have oxygen in them are the pulmonary veins. The definition of a vein is a blood vessel that carries blood to the heart. This blood is usually de-oxygenated, but the pulmonary veins are the exception.
Varicose Veins 2nd answer: . . . or, blood vessels with less oxygen are veins?
