The combining form esophag- denotes which organ?

• A. Stomach
• B. Liver
• C. Intestine
• D. Esophagus

Answer: (D)

Combining forms in medical terminology name the organs involved, and esophag- denotes the esophagus. This tube carries food from the throat to the stomach, so when you see esophag- (often written as esophag/o) it points to that structure. It appears in terms like esophagitis (inflammation of the esophagus) or esophagoscopy (visual examination of the esophagus). Other options refer to different organs: gastr/o for the stomach, hepat/o for the liver, and enter/o for the intestines, not the esophagus.
