Which prefix means kidney?

Which prefix means kidney?

• A. ren/o
• B. semin/i
• C. urin/o
• D. testicul/o

Answer: (A)

Ren/o denotes the kidney. It comes from the Latin renes and is used in medical terms describing kidney-related structures and functions, such as renal artery, renal function, and renography. The other prefixes point to different parts: semin/o relates to semen, testicul/o to the testicle, and urin/o to urine, so they do not mean kidney. A secondary kidney-forming prefix you might see is nephr/o, which serves a similar purpose in many terms (nephrology, nephron), but ren/o specifically names the kidney in many common terms.
