The root 'ven/o-' refers to which structure?

• A. Artery
• B. Heart
• C. Capillary
• D. Vein

Answer: (D)

ven/o- designates a vein. Veins are the blood vessels that return blood toward the heart, which is why you see venous, venipuncture, venography in medical terms. This contrasts with arteri/o- for arteries (blood vessels that carry blood away from the heart) and capill/o- (or capill/i-) for capillaries, the tiny vessels between arteries and veins. So the root ven/o- refers to the vein.
