Question

helps move food into the opening of the esophagus

Answer 1

The muscle responsible for moving food into the opening of the esophagus is the upper esophageal sphincter, which relaxes to allow food to pass into the esophagus. The process of swallowing (also known as deglutition) involves coordinated contractions of muscles in the mouth and throat to push the food towards the esophagus. Additionally, the tongue helps to manipulate the food and propel it towards the back of the throat. Drinking liquids can also help to facilitate the movement of food into the esophagus.
