Detailed explanation-1: -A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach. This valve opens to let food pass into the stomach from the esophagus and it prevents food from moving back up into the esophagus from the stomach.
Detailed explanation-2: -The cardiac sphincter that lies at the lower end of the esophagus acts like a valve that ensures unidirectional flow of ingested food. To be more precise, it is located between the distal end of the esophagus and the stomach.
Detailed explanation-3: -The lower esophageal sphincter (LES), also known as the cardiac sphincter, is an involuntary sphincter located at the bottom of the esophagus, where it connects with the stomach.
Detailed explanation-4: -The cardia is the first part of the stomach, which is connected to the esophagus. It contains the cardiac sphincter, which is a thin ring of muscle that helps to prevent stomach contents from going back up into the esophagus.
