Which term describes something 'within a vein'?

• A. Intravascular
• B. Intraarterial
• C. Intravenous
• D. Intracellular

Answer: (C)

Understanding that medical prefixes tell you where something is located helps identify that something within a vein is described as intravenous. The prefix intra- means inside, and ven- relates to veins, with the -ous ending forming an adjective. So intravenous refers specifically to something within or administered into a vein, such as an intravenous drip or IV injection. Intravascular is broader, meaning inside any vessel (vein or artery), so it’s not as precise for a vein alone. Intraarterial means inside an artery, not a vein. Intracellular means inside a cell, which is a completely different compartment. Therefore, the term that describes something within a vein is intravenous.
