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.
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 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 function of the cardiac sphincter is to prevent a back flow of materials back into the esophagus. The cardiac sphincter closes to allow the food to stay within the stomach so it can be digested. Cardiac sphincter, working with the pyloric sphincter keeps the stomach content from moving elsewhere.
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.
A sphincter is a ring-like muscle that contracts and relaxes to control the flow of substances in and out of a body cavity. It acts as a valve to regulate the passage of food, liquids, and waste in various parts of the body, such as the digestive tract and urinary system.
It relaxes because of the hormone progesterone allowing food to come back to the esophagus.
The cardiac sphincter.
The Cardiac sphincter prevents regurgitation of food from the stomach.
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 esophageal sphincter ,which allows food to enter the stomach, and stops the acidic contents from entering the esophagus.
It is known as the lower esophageal sphincter or sometimes the cardioesophageal 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 pyloric sphincter opens in response to the presence of food in the stomach. This triggers a reflex that relaxes the sphincter, allowing food to pass into the small intestine. The sphincter closes to prevent the backflow of intestinal contents back into the stomach.
