What is the purpose of gastroesophageal reflux scans?
The purpose of gastroesophageal reflux scanning is to allow the doctor to visualize the interior of the patient's upper stomach and lower esophagus.
What does the cardiac sphincter do in the digestive system?
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 does the act of swallowing cause?
causes a wave of esophageal contraction called peristalsis. Peristalsis pushes food along the esophagus. Normally, peristalsis causes the esophageal sphincter to relax and allow food into the stomach.
What are the functions of a cardiac sphincter?
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.
What is between stomach and small intestine?
The opening between the stomach and the small intestine is called the Pyloric Sphincter- it is a ring of muscle that contracts when the stomach is full, to seal off the opening to the small intestine whilst foodstuffs are liquified in the stomach. When this has been done, the sphincter muscle relaxes, re-opening the channel to allow the liquified nutrients into the intestines.
How does the cardiac and pyloric help with digestion and absorpation?
The pyloric sphincter is a valve that opens and closes to allow chyme to leave the stomach and enter the duodenum. The cardiac sphincter is a valve that opens and closes to prevent stomach acid from going up the esophagus.
What is the function of sphincter?
The Sphincter is a valve at the opening and the exiting ends of the stomach. The sphincter helps keep food that has been swallowed, where it should be, in the stomach. It also helps to digest the food at a slow rate, to keep the body fuller for longer.
What is the cardioesophageal sphincter?
The oesophagus is the first part of the alimentary tract after the oropharynx. The cardio-oesophageal junction is the point where the oesophagus meets the stomach (at it's cardiac end - meaning the part of the stomach closer to the heart), where there is a circumferential thickening of the muscles in the wall of the gastrointestinal tract (tube). This extra thickening in the muscle layer is called the cardio-oesophageal sphincter. When food swallowed reaches this part, the sphincter dilates (expands/opens) to allow food to pass through from the oesophagus to the stomach. Once the food passes, the sphincter contracts (narrows/closes down) to prevent the contents of the stomach from returning back to the oesophagus. Regurgitation of stomach contents and resultant vomiting occurs when the functioning of this sphincter becomes defective.

What is the purpose of sphincters in the stomach?
there 2 kinds of sphincters the cardiac and pyloric the cardiac prevents the bolus from going back to the oesophagus cardiac sphincters allows the bolus to enter the stomach the pyloric sphincters prevents food from going to the duodenum the pyloric sphincter allows the chyme to enter the duodenum hope it was helpful :)
Where is pyloric sphincter located?
Pyloric sphincter is located at the base of the stomach and is the contracting ring of muscle which guards the entrance of the to small intestine.It keeps the stomach shut at the far end so that it has a chance to digest proteins, then it opens and allows the contents of the stomach, now called chyme, to pass through the pyloric sphincter and enter the small intestine; the first section is called the duodenum and it does the majority of digestion and some absorption.It controls the emptying of chyme into duodenum.
What is the function of the plyoric muscle?
The pyloric muscle is in a ring shape and is responsible for keeping the pyloric sphincter closed , until it is time to allow some of the contents of the stomach to enter the small intestine.
