Which combining form refers to the kidney?

Which combining form refers to the kidney?

• A. Liver
• B. Bladder
• C. Kidney
• D. Heart

Answer: (C)

Combining forms are roots used to build medical terms that name body parts. For the kidney, the standard roots are nephr/o (from Greek) and ren/o (from Latin). These roots connect with suffixes to form words like nephrology (the study of the kidney) or renal (pertaining to the kidney). The options shown are names of organs rather than combining forms, so they don’t provide the correct kidney-related root. If you’re naming the kidney in a term, you’d use nephr/o or ren/o. For reference, the liver uses hepat/o, the bladder uses cyst/o, and the heart uses cardi/o, none of which refer to the kidney.
