The cardiac sphincter, also known as the lower esophageal sphincter (LES), is a ring of muscle located at the junction of the esophagus and the stomach. Its primary function is to prevent the backflow of stomach contents, including acid, into the esophagus. This sphincter relaxes to allow food to enter the stomach and constricts to keep stomach contents contained, helping to maintain proper digestive function. Dysfunction of the cardiac sphincter can lead to conditions such as gastroesophageal reflux disease (GERD).
The cardiac sphincter is the valve between the esophagus and the stomach.
The structure located between the esophagus and the stomach is the lower esophageal sphincter (LES). The LES is a muscular valve that opens to allow food to enter the stomach and closes to prevent stomach contents from flowing back up into the esophagus.
If the cardiac sphincter relaxes, it allows stomach contents to reflux back into the esophagus, causing acid reflux or heartburn. This can lead to symptoms like chest pain, regurgitation, and a sour taste in the mouth. Chronic relaxation of the cardiac sphincter can contribute to gastroesophageal reflux disease (GERD).
mild pain burping after food
The cardiac sphincter, also known as the lower esophageal sphincter, may malfunction due to various reasons such as hiatal hernia, obesity, smoking, certain medications, and certain foods that can relax the sphincter muscle. This dysfunction can lead to conditions like gastroesophageal reflux disease (GERD) and heartburn.

What is the function of the cardiac sphincter?
What is the function of the cardiac sphincter?
The sphincter at the top of the stomach is called the cardiac sphincter because it is located near the heart, which is known as the cardiac region. This sphincter helps regulate the passage of food from the esophagus into the stomach, preventing backflow of stomach contents into the esophagus.
The Cardiac sphincter prevents regurgitation of food from the stomach.
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.
At the cardiac orifice of the stomach which separates the stratified squamous epithelium of the esophagus from the columnar epitheilium of the stomach. in simpler terms, its between the esophagus and the stomach
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.
cardiac sphincter/lower esophageal sphincter (LES)
The cardiac sphincter and the pyloric sphincter.
the cardiac sphincter opens involuntarily during peristalsis, which is the process of wavelike muscle contractions of the alimentary tract that moves food along the oesophagus down to the stomach. :)
The circular ring of muscle located at the entrance and exit of the stomach is referred to as a "sphincter" - the one at the entrance to the stomach is referred to as the cardiac sphincter, and the one at the exit of the stomach to the small intestines is referred to as the pyloric sphincter.
