Ren- is the combining form for which of the following?

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

Answer: (A)

Recognizing combining forms helps you see how medical terms are built. Ren- is the Latin root for kidney and serves as the combining form when naming or describing the kidney. When you add a vowel to connect it, you often get ren/o-, which appears in terms like renography or renin. The adjective renal means related to the kidney, showing how this root functions in practice. For contrast, the heart uses cardio- or coron/o-, the lung uses pulmon/o- or pneumon/o-, and the liver uses hepat/o- or hepatic-. Each organ has its own set of roots, which is why ren- specifically points to the kidney.
