What sphincter that opens when food or fluids exert pressure on it?
The sphincter that opens when food or fluids exert pressure on it is the gastroesophageal sphincter. Closure of the sphincter is under the control of the vagus nerve.
What causes the gastroesophageal sphincter to open to allow food to enter the stomach?
the arrival of the peristaltic wave at the stomach
The sphincter muscle that controls access to the stomach from the esophagus is called?
cardiac sphincter; or gastroesophageal sphincter; or lower esophageal sphincter (LES); or esophageal sphincter from http://en.wikipedia.org/wiki/Cardia
When the cardiac sphincter relaxes food enters the?
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.
Ring like muscle that controls the flow from the stomach to the small intestine?
lower esophageal sphincter or gastroesophageal sphincter
Sphincter found between the esophagus and the stomach?
What is the function of the cardiac sphincter?
The stomach sphincter that keeps food from reentering the esophagus when the stomach contracts is known as the?
It is known as the lower esophageal sphincter or sometimes the cardioesophageal sphincter.
Is cardioesophageal and gastroesophageal same thing?
No. Cardio- = heart Gastro- = stomach Esophageal = of or pertaining to the esophagus Edit- Yes. The Lower Esophageal Sphincter (LES) is also referred to as the Cardioesophageal Sphincter and the Gastroesophageal Sphincter. This sphincter separates the esophagus from the stomach and is usually in a closed position. When there is weakness in the sphincter gastric juices may go up into the esophagus resulting in heartburn.

What muscle prevents food from returning to the oesophagus from the stomach?
The muscle that prevents food from returning to the esophagus from the stomach is the lower esophageal sphincter (LES). This circular band of muscle relaxes to allow food to enter the stomach and then contracts to prevent the backflow of stomach contents. Proper functioning of the LES is essential to prevent conditions like acid reflux or gastroesophageal reflux disease (GERD).
Pyloric sphincter function?
The pyloric sphincter is a muscular valve that controls the flow of partially digested food (chyme) from the stomach to the small intestine. It regulates the release of chyme in small amounts to ensure proper digestion and absorption of nutrients. Dysfunction of the pyloric sphincter can lead to conditions like gastritis, peptic ulcers, and gastroesophageal reflux disease.
Sphincter controlling the movement of food from the stomach into the duodenum?
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
