Gastro oesophageal reflux is a condition where the acidic content of the stomach regurgitates back into the oesophagus. The distal oesophageal mucosa is non glandular in type (it is squamous epithelium), therefore, it can easily be damaged by chronic acid reflux.
To prevent this, there are several mechanisms in place:
To prevent stomach contents from refluxing back into the esophagus.
The structure that separates the stomach and esophagus is called the lower esophageal sphincter (LES). This muscular ring is located at the junction of the esophagus and stomach and functions to prevent the backflow of gastric contents into the esophagus. When functioning properly, the LES opens to allow food to enter the stomach and closes to protect the esophagus from acidic stomach contents. Dysfunction of the LES can lead to conditions such as gastroesophageal reflux disease (GERD).

The peristaltic movements are muscle contractions and its function on the esophagus is to push food down into the stomach and prevent it from going back into the esophagus.
The gatekeeper of the esophagus is called the lower esophageal sphincter (LES). It is a muscular ring at the junction of the esophagus and stomach that helps to prevent stomach acid from flowing back into the esophagus.
It is called the "gag reflex." It is really one of the body's defense mechanisms to prevent foreign matter from entering the esophagus. You may have experienced this at the doctor's office when they place the tongue depressor far back on your tongue.
The esophagus-stomach valve, also known as the lower esophageal sphincter, is a muscle that controls the flow of food and liquids from the esophagus into the stomach. Its main function is to prevent stomach contents from flowing back up into the esophagus, helping to prevent acid reflux and heartburn.

The esophagus is connected to the stomach through a muscular valve called the lower esophageal sphincter. This valve opens to allow food to pass from the esophagus into the stomach and then closes to prevent stomach contents from flowing back up into the esophagus.

Esophageal sphincter or known as cardia. It prevents the acids and stomach contains to re-enter the esophagus.
The lower esophageal sphincter is a ring of muscle at the bottom of the esophagus that acts as a valve to prevent stomach acid from flowing back into the esophagus. When functioning properly, it closes tightly after food passes into the stomach, creating a barrier that helps prevent acid reflux and heartburn.
