Which combining form relates to the intestines?

• A. Nephr/o
• B. Viscer/o
• C. Enter/o
• D. Coron/o

Answer: (C)

Identifying the combining form that means the intestines. Enter/o is the combining form for the intestines, used in terms like enteritis, enteral, and enterology. It specifically names the intestinal tract, which is why it’s the correct choice here. Nephr/o refers to the kidneys, viscer/o to internal organs or viscera in general, and coron/o relates to the heart or a crown-like structure, not the intestines.
