Which combining form means kidney?

Which combining form means kidney?

• A. rhin(o)
• B. ren(o)
• C. pyo-
• D. quadr(i)-

Answer: (B)

Ren/o denotes kidney. In medical terms, this combining form attaches to roots to form words about the kidneys, such as renal (relating to the kidney) or renin (an enzyme produced by the kidneys). The other options refer to different things: rhin(o) means nose, pyo- means pus, and quadr(i)- indicates four or a quadrant, not an organ.
