The name of the sphincter between the esophagus and the stomach is called the LES, or lower esophageal sphincter.
The cardiac sphincter is the valve between the esophagus and the stomach.
There is no anatomical sphincter present at junction between stomach and esophagus. The angle formed by greater curvature of stomach demarcates the two organs.
What is the function of the cardiac sphincter?
The sphincter located between the esophagus and the fundus of the stomach is called the lower esophageal sphincter (LES). It is a muscular ring that opens to allow food to enter the stomach and then closes to prevent stomach acid from flowing back into the esophagus.
At the cardiac orifice of the stomach which separates the stratified squamous epithelium of the esophagus from the columnar epitheilium of the stomach. in simpler terms, its between the esophagus and the stomach
The muscular door between the esophagus and stomach is called the lower esophageal sphincter (LES). This sphincter helps prevent stomach acid and contents from flowing back up into the esophagus. Dysfunctional LES can lead to conditions like gastroesophageal reflux disease (GERD).
The lower esophageal sphincter guards the entrance of the stomach from the esophagus.
The structure located between the esophagus and the stomach is the lower esophageal sphincter (LES). The LES is a muscular valve that opens to allow food to enter the stomach and closes to prevent stomach contents from flowing back up into the esophagus.
Pyloric Sphincter
The cardiac sphincter or aka GE junction contracts at the distal end of the esophagus. So food enters into the stomach when the cardiac sphincter is relaxed.
Esophageal sphincter or known as cardia. It prevents the acids and stomach contains to re-enter the esophagus.
The connection between the esophagus and duodenum is through the stomach, specifically the lower esophageal sphincter and the pyloric sphincter. Food travels from the esophagus to the stomach through the lower esophageal sphincter and then from the stomach to the duodenum through the pyloric sphincter.
