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.
esophagal sphinter is a sphincter is actullal found there end of esophagous,
I can think of 5 off the top of my head. Cardiac Sphincter at the top of the stomach. Pyloric Sphincter at the distal end of the stomach. Ileocecal Valve that separates the Small and Large intestines and the Internal and External Anal sphincters.
The esophageal sphincter ,which allows food to enter the stomach, and stops the acidic contents from entering the esophagus.
A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
The sphincter at the distal end of the common bile duct that controls the flow of bile into the duodenum is called the sphincter of Oddi. This muscular structure regulates the release of bile and pancreatic juice into the small intestine, aiding in digestion. It opens in response to hormonal signals, particularly when food enters the duodenum.
Yes, there are two on the distal end and one on the proximal end. Distally there are the internal and external anal sphincters. Proximally there is the ileocecal valve.
The cardiac sphincter.
The spincters located in the esophagus are: the upper sphincter at the top and the lower (the cardiac sphincter) at the bottom of the esophagus. They regulate the food passing through the esophagus.
I will take a guess at this question. I think it is the Cardiac Sphincter.
Sphincters are circumferential muscles that can relax or constrict to regulate the passage of material through a particular area. The stomach is bound by two sphincters in humans: the lower esophageal sphincter that keep stomach acid in the stomach and the pyloric sphincter that regulates the flow of food in the stomach into the duodenum.
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.
