Detailed explanation-1: -Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach. A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach.
Detailed explanation-2: -The primary function of the esophagus is to transport food entering the mouth through the throat and into the stomach.
Detailed explanation-3: -The esophagus is a narrow, muscular tube that leads from the mouth to the stomach. The esophagus carries food from the mouth to the stomach. A sphincter at the junction of the esophagus and the stomach prevents reflux of food and acid from the stomach into the esophagus.
Detailed explanation-4: -Peristalsis squeezes your esophageal muscles from top to bottom. This pushes food and liquid along. If you could see peristalsis, it would look like a wave passing down your esophagus. To keep food and liquids moving in the right direction, your digestive tract has special muscles along its course called sphincters.
