The lower esophageal sphincter, or gastroesophageal sphincter, surrounds the lower part of the esophagus at the junction between the esophagus and the stomach. It is also called the cardiac sphincter or cardioesophageal sphincter, named from the adjacent part of the stomach, the cardia.

Is there a valve in your stomach? The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

What causes stomach sphincter muscle not to work? Gastroesophageal reflux disease (GERD)This occurs when the lower esophageal sphincter (LES) does not work properly. This can be due to a weak sphincter muscle, too-frequent spontaneous relaxations of the sphincter, or hiatal hernia.

What is the flap that covers your esophagus? A small muscular flap (epiglottis) closes to prevent food and fluids from going down the windpipe (trachea) toward the lungs.

What causes a damaged esophagus? Reflux esophagitis is caused by a reflux of stomach acid into the esophagus. This can lead to erosive esophagitis. Causes of eosinophilic esophagitis include food allergies, gastroesophageal reflux disease (GERD), parasitic diseases, or inflammatory boweldiseases.
