Question: The movement of food in food pipe is called?

context: Food is mechanically broken down by the action of the teeth controlled by the muscles of mastication (V) acting on the temporomandibular joint. This results in a bolus which is moved from one side of the oral cavity to the other by the tongue. Buccinator (VII) helps to contain the food against the occlusal surfaces of the teeth. The bolus is ready for swallowing when it is held together by saliva (largely mucus), sensed by the lingual nerve of the tongue (VII—chorda tympani and IX—lesser petrosal) (V). Any food that is too dry to form a bolus will not be swallowed.
question: What is the mechanical action that moves food into the esophagus?
short_answers: swallowing
context: Food is ingested through the mouth and when swallowed passes first into the pharynx and then into the esophagus. The esophagus is thus one of the first components of the digestive system and the gastrointestinal tract. After food passes through the esophagus, it enters the stomach. When food is being swallowed, the epiglottis moves backward to cover the larynx, preventing food from entering the trachea. At the same time, the upper esophageal sphincter relaxes, allowing a bolus of food to enter. Peristaltic contractions of the esophageal muscle push the food down the esophagus. These rhythmic contractions occur both as a reflex response to food that is in the mouth, and also as a response to the sensation of food within the esophagus itself. Along with peristalsis, the lower esophageal sphincter relaxes.
question: What is the autonomic function that moves food from the esophagus to the stomach?
short_answers: peristalsis

Answer: The mechanical action that moves food into the esophagus is called swallowing. Swallowing is an important part of eating and drinking. The autonomic function that moves food from the esophagus to the stomach is called peristalsis. In much of a digestive tract such as the human gastrointestinal tract, smooth muscle tissue contracts in sequence to produce a peristaltic wave, which propels a ball of food along the tract.
