Answer Contractions of the muscles move the Bolus to a Valve called the CARDIAC SPHINCTER VALVE where the Esophagus joins the Stomach.? The Sphincter allows food to pass into the stomach but usually NOT Letting it move Back Up into the Esophagus. This therefore prevents gastroesophageal reflux disease (gastric reflux)
What is the function of the cardiac sphincter?
The ring shaped muscle in the digestive system is the lower esophageal sphincter (LES).
The Cardiac sphincter prevents regurgitation of food from the stomach.
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.
I will take a guess at this question. I think it is the Cardiac Sphincter.
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 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 pyloric sphincter regulates passage of chymefrom the stomach
Bolus goes down esophagus, through lower esophageal sphincter (aka, cardiac sphincter) and into stomach. (A sphincter is a circular muscle which squeezes shut or opens the tubular digestive tract). It then passes through pyloric sphincter into small intestine. The small intestine is made up first of the duodenum, then jejunum, then ileum. From ileum, bolus goes to ascending colon, then transverse colon, then descending colon. From there to rectum and then out through anus (anal sphincter) .
cardiac sphincter/lower esophageal sphincter (LES)
The cardiac sphincter and the pyloric sphincter.
The cardiac sphincter is the valve between the esophagus and the stomach.
