The peristaltic movements are muscle contractions and its function on the esophagus is to push food down into the stomach and prevent it from going back into the esophagus.

A peristaltic wave typically begins in the esophagus when you swallow food or liquids. This wave of muscle contractions helps move the food through the digestive system.
The frequency of peristaltic movement can vary depending on the location in the body. In the small intestine, for example, peristalsis occurs approximately 8-12 times per minute. In the esophagus, peristalsis typically occurs at a rate of about 3-4 times per minute.

The main organ responsible for the propulsion of food through the gastrointestinal (GI) tract is the esophagus. Its function is largely mechanical, as it uses peristaltic waves of muscle contractions to push food from the mouth to the stomach.
The esophagus is not directly involved in chemical digestion. Its main function is to transport food from the mouth to the stomach using peristaltic contractions. Chemical digestion primarily occurs in the stomach and small intestine, where enzymes break down food into nutrients that can be absorbed by the body.
You are thinking of the esophagus, the food pipe that connects the mouth to the stomach.
