What term describes the digestive tract from the mouth to the anus?

• A. Alimentary canal
• B. Digestive system
• C. Gastrointestinal tract
• D. Alimentary tube

Answer: (A)

The term describes the continuous hollow passage through which food travels from mouth to anus: the alimentary canal. This tube includes the esophagus, stomach, and intestines where digestion, absorption, and finally elimination occur. The digestive system, while related, also includes external organs like the liver, pancreas, and gallbladder, which assist digestion but aren’t part of the tube itself. The gastrointestinal tract is another common name for this same tube, but the precise term for the pathway from mouth to anus is the alimentary canal. The phrase alimentary tube is less standard in anatomical usage.
