The combining form cardi/o denotes which body region?

• A. Heart
• B. Liver
• C. Stomach
• D. Brain

Answer: (A)

Combining forms are bits of a word that connect to suffixes or other roots. cardi/o means the heart, coming from Greek kardia. This is seen in terms like cardiology (the study of the heart), cardiac muscle, and cardiogram, all clearly relating to the heart. The other options point to different body regions: hepat/o for liver, gastr/o for stomach, and cerebr/o/encephal/o for the brain.
