The suffix -stenosis indicates which concept?

• A. Choking
• B. Narrowing
• C. Crushing
• D. Development

Answer: (B)

Understanding medical suffixes that describe a change in a passage or vessel. The ending -stenosis means narrowing or constriction of a lumen. It’s used to name conditions where a blood vessel or a passage becomes smaller, such as aortic stenosis (narrowing of the aortic valve opening) or renal artery stenosis (narrowing of a kidney artery). That’s why narrowing is the best choice here.

Choking isn’t a suffixal meaning and describes a symptom of obstruction rather than a structural narrowing described by a suffix. Crushing refers to forceful breaking or compressing and isn’t conveyed by -stenosis. Development points to growth or formation, which is usually indicated by endings like -plasia or -genesis, not -stenosis.
