The sphincter that opens when food or fluids exert pressure on it is called the lower esophageal sphincter (LES).
Lower esophageal sphincter is the sphincter that opens when food or fluid exert pressure on it. It is located at the junction of the esophagus and stomach, allowing food to enter the stomach after swallowing.
The gastrointestinal tract contains sphincters, which are circular muscles that regulate the movement of material through the digestive system. Some examples of sphincters in the gastrointestinal tract include the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
Abnormal esophageal function tests may show evidence of dysmotility, such as ineffective esophageal peristalsis, impaired lower esophageal sphincter relaxation, or high-amplitude contractions. Other characteristics can include prolonged esophageal acid exposure, abnormal response to acid exposure, or non-acid reflux events. These abnormalities may indicate conditions such as gastroesophageal reflux disease (GERD), esophageal motility disorders, or other functional disorders of the esophagus.
The esophageal sphincter is a muscular ring at the junction of the esophagus and stomach. It helps prevent stomach acid and food from regurgitating back into the esophagus by contracting to close off the passage between the two organs. When we swallow, the sphincter relaxes to allow food to enter the stomach.

Another name for the esophageal sphincter is the lower esophageal sphincter (LES).
The lower esophageal sphincter must open to allow for vomiting. This sphincter is located at the junction of the esophagus and stomach, and its relaxation allows the contents of the stomach to be expelled back up through the esophagus.

Another name for the esophageal sphincter is the lower esophageal sphincter (LES). It is a muscular ring located at the bottom of the esophagus that helps prevent stomach contents from flowing back up into the esophagus.
The lower sphincter is responsible for reflux problems
The sphincter that opens when food or fluids exert pressure on it is called the lower esophageal sphincter (LES).
Esophageal achalasia is the term used for the failure of the lower esophageal sphincter to relax, resulting in functional obstruction of the esophagus, and dysphagia. There is total absence of peristalsis of esophagus, and failure of the lower esophageal sphincter to relax when food or liquid is swallowed. This gives rise to vomiting of food or liquid as soon as it is swallowed. There really isn't any cause but there are some guesses none are proven.
