During peristalsis, the esophageal sphincter allows the food bolus to pass into the stomach. It prevents chyme, a mixture of bolus, stomach acid, and digestive enzymes, from returning up the esophagus. An overly loose esophageal sphincter leads to heart burn because the stomach acid "burns" the esophagus. An overly tight esophageal sphincter is known as achalasia and leads to pain on swallowing, regurgitation of food, and cheat pain.

Sphincter that opens when food or fluid exert pressure on it?
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.
What conditions is characterized incompetence of the esophageal sphincter?
Incompetence of the esophageal sphincter is primarily characterized by gastroesophageal reflux disease (GERD). This condition occurs when the lower esophageal sphincter fails to close properly, allowing stomach acids to flow back into the esophagus, leading to symptoms such as heartburn, regurgitation, and difficulty swallowing. Other conditions associated with sphincter incompetence include hiatal hernia and esophagitis, which can exacerbate the reflux symptoms.
What vessel contains sphincter?
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.

What sphincter is involved in Acid reflux disease?
cardiac sphincter/lower esophageal sphincter (LES)
What sphincter must open to permit vomiting?
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.
