Which prefix means kidney?

Which prefix means kidney?

• A. Plexus
• B. Encephal-
• C. Colp(o)-
• D. Ren-

Answer: (D)

Ren- signals kidney in medical terms. It comes from the Latin word ren, renis, which forms words like renal and renography to indicate kidney-related structures or functions. The other options refer to completely different parts or concepts—plexus means a network, encephal- relates to the brain, and colpo- refers to the vagina—so they don’t indicate the kidney. In practice, you’ll also see the combining form ren/o- used when joining with other roots, but the idea remains that ren- points to the kidney.
