What is the tube that connects the mouth to the stomach?

• A. Stomach
• B. Esophagus
• C. Small intestine
• D. Large intestine

Answer: (B)

Transport of swallowed food through the digestive tract is carried out by a muscular tube that moves content downward with coordinated contractions. That tube is the esophagus, which runs from the back of the throat to the stomach and uses peristaltic waves to push the bolus down. It doesn’t digest food; its job is to deliver food to the stomach, where digestion begins with acid and enzymes. The stomach acts as a mixing chamber and chemical digester, the small intestine is where most digestion and nutrient absorption occur, and the large intestine handles water absorption and waste formation. The esophagus also has sphincters that regulate entry into the stomach and help prevent reflux.
