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: -After ingestion and mastication, the food particles move from the mouth into the pharynx, then into the esophagus. This movement is deglutition, or swallowing. Mixing movements occur in the stomach as a result of smooth muscle contraction.
Detailed explanation-3: -More Information. Anatomy of the digestive system. The digestive system is made up of organs that are important for digesting food and liquids. These include the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus.
