Which prefix denotes a vein?

• A. Vas-
• B. Phleb-
• C. Veno-
• D. Athero-

Answer: (B)

Phleb- is the prefix that denotes a vein. It comes from the Greek phleps, meaning vein, and appears in terms like phlebitis (vein inflammation), phlebotomy (drawing blood from a vein), and phlebography (imaging of veins). This makes it specifically tied to veins rather than to blood vessels in general or to other structures. Vas- refers to vessels in a broad sense, veno- is also used in some vein-related terms but is not as consistently vein-specific in many medical terms, and athero- means plaque buildup. So phleb- best signals a vein.
