A combination of your tongue and jaw muscles
smooth muscles in the wall of the esophagus.
The esophagus is the digestive organ that moves food from the mouth to the stomach. No digestion, only transport, happens in the esophagus.
The process of swallowing ensures that food goes down the esophagus. When you swallow, a series of coordinated muscle contractions called peristalsis moves the food bolus from the throat into the esophagus. Additionally, a flap of tissue called the epiglottis prevents food from entering the windpipe, directing it instead toward the esophagus. This combination of muscle action and anatomical structures ensures that food reaches the stomach efficiently.

Peristalsis is the term for the wavelike motions of the esophagus.
The esophagus takes the food from the mouth to the stomach. Food moves through the esophagus by peristalsis, which is muscle contractions the pushes the food downward. At the end of the esophagus is the lower esophageal sphincter (LES), which prevents food from re-entering the esophagus after it's reached the stomach.
The esophagus is a tube made of smooth muscle. It carries food from throat to stomach. The muscular movements of peristalsis moves the food downward, as well as by gravity. However, you can be upside down and food will still get to the stomach.
The contractions in the esophagus are called peristalsis. This coordinated, wave-like muscle movement helps to propel food from the throat down to the stomach. Peristalsis is essential for swallowing and ensures that food moves efficiently through the digestive tract.
Saliva in the mouth moistens the food, while mastication (chewing) breaks the food into pieces. These enter the esophagus where gravity, the circular action of sliding against smooth muscle, and slight peristalsis moves the food into the stomach. Peristalsis is similar to gentle waves within the muscle walls of the esophagus. Peristalsis only and always moves in one direction: downward. Peristalsis in the intestines is stronger.gravity my friend. gravity.
Smooth muscles make up most of the esophagus, but the upper portion also contains some voluntary or skeletal muscle. The muscles move in a wave like pattern to move food down into the stomach through a process called "peristalsis". At the distal end is the lower esophageal sphincter, a ring of smooth muscle that controls movement of food between the stomach and esophagus.
Your esophagus moves it so even when you eat upside down it will still go to your stomach. The series of muscle relaxations (infront of the bolus) and contractions (behind the bolus) that moved food down the esophagus is called peristalsis.
The esophagus moves food downward without performing any digestive functions.
