What is the name given to movement of food along oesophagus?

The name given to the movement of food along the oesophagus is peristalsis. Peristalsis is a series of involuntary, coordinated muscle contractions that propel food from the mouth to the stomach. These contractions begin in the upper oesophagus and progress downward, pushing the food bolus along the oesophagus. The oesophageal sphincters, which are circular muscles located at the upper and lower ends of the oesophagus, relax and allow the food bolus to pass through. Peristalsis is controlled by the nervous system and is essential for the proper digestion of food.
