What does VAS stand for?

• A. Blood vessel
• B. Vessel
• C. Heart
• D. Vein

Answer: (B)

VAS is built from the root vas-, which means vessel. In medical terminology, this root refers to any vessel in the body that carries fluids, not a specific kind. So the expansion that fits best is vessel, the general term for any hollow tube like arteries, veins, or ducts. Saying blood vessel would be narrowing it to one type, and heart or vein would use different roots (cardi- for heart, specific vein terminology for veins). The idea is to recognize vas- as indicating a vessel in general, which is why vessel is the correct expansion.
