A combination of your tongue and jaw muscles
The esophagus contains varying amounts of striated muscle.
peristalsis concentric contractions of the muscles in your esophagus
smooth muscles in the wall of the esophagus.
Food is moved along the esophagus through a process called peristalsis, which involves the contraction and relaxation of muscles in the esophagus. These muscle contractions create wave-like movements that push the food towards the stomach. Additionally, gravity helps to move food downward as you swallow.
The esophagus has two types of muscles. The upper third of the esophagus is composed of striated muscles, while the lower third contain smooth muscles. The muscles in the middle are a mixture of both striated and smooth.
muscles lining the esophagus move in a wavelike motion, oushing the food through the esophagus and into the stomach
Swallowing involves the coordinated effort of over 25 muscles, including muscles in the mouth, jaw, throat, and esophagus. These muscles work together to move food or liquid from the mouth to the stomach in a process called deglutition.
