Dear Student,
The gastroesophageal sphincter is the valve at the top of the
stomach that allows food to enter the stomach from the esophagus
When it is closed, the gastroesophageal sphincter maintains a
higher pressure than that of the stomach so that food and digestive
juices cannot wash back into the esophagus
Hope this helps,
Cheers !!
