Esophagus function?

Explanation:
The esophagus is a muscular tube whose main job is to move swallowed material from the pharynx down to the stomach using coordinated muscle contractions called peristalsis. This transport occurs after you swallow, with the upper esophageal sphincter opening to let the bolus pass into the esophagus and the lower esophageal sphincter relaxing to deliver the food into the stomach. It does not absorb nutrients—the small intestine handles most absorption—and it does not produce bile—the liver makes bile. The esophagus’s role is therefore about conveying the food downward, rather than ingesting or processing it.
