Which body system includes the esophagus?

• A. Nervous
• B. Respiratory
• C. Circulatory
• D. Digestive

Answer: (D)

The esophagus is a conduit in the digestive system. It forms part of the alimentary canal that carries swallowed material from the mouth to the stomach. It uses coordinated muscle contractions (peristalsis) and mucus to move the bolus downward, preparing it for digestion and absorption that occurs later in the stomach and intestines. While the nervous system helps regulate the choking and movement through neural signals, and the respiratory and circulatory systems interact with digestion in other ways, the esophagus’s primary role is within the digestive system.
