Esophagus
smooth muscle
The muscles found in the esophagus and intestines are primarily smooth muscles, which are involuntary and not under conscious control. In the esophagus, these muscles facilitate the movement of food through peristalsis, while in the intestines, they help in the digestion and movement of food along the gastrointestinal tract. Smooth muscle contractions in these areas are essential for proper digestive function.

No. It does occur in the esophagus, however.

The esophagus contains varying amounts of striated muscle.
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.
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 muscles at the bottom of the esophagus, known as the lower esophageal sphincter (LES), function to control the passage of food from the esophagus into the stomach. They contract to prevent the backflow of stomach contents, including acid, into the esophagus, thus protecting the esophageal lining from damage. Proper function of the LES is crucial in preventing gastroesophageal reflux disease (GERD).
