What is a sphincter in the digestive system?
The pyloric sphincter regulates passage of chymefrom the stomach
What slows intestinal motility and causes the pyloric sphincter to contract?
the pyloric sphincter regulates the speed at which the chyme (mixture of food from stomach) can enter into the small intestine to be digested. The pyloric sphincter opens and closes according to the acidity of the chyme.
Valve preventing movement of chyme from the duodenum into the stomach?
The pyloric sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives sympathetic innervation from celiac ganglion. http://en.wikipedia.org/wiki/Pylorus
How does pyloric sphincter knows to open for chyme and when to close?
It is a combination of hormones, brain signals, and sensor tissue near the sphincter.
What is the muscle that controls flow from stomach?
The pyloric sphincter regulates the passage of chyme into the duodenum (sm. intestine).
How does the food get from the stomach to the small intestine?
The food in the stomach are known as chyme at this stage. The pyloric sphincter (a muscle) ensures that chyme is released bit by bit into the small intestine.
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 allows chyme to enter the small intestine?
mechanical digestion is essentially complete, but the other processes are ongoing or have not yet begun
What controls the amount of chyme entering that small intestine?
The pyloric sphincter regulates the entry of chyme into the duodenum.
What is one function of the pyloric valve?
It serves to regulate the movement of food out of the stomach and prevents bile in the small intestine from moving back into the stomach.
What is the muscle that opens and closes the entrance from the stomach to the duodenum?
The pyloric sphincter muscle regulates the flow of chyme from the stomach to the duodenum just a few mL at a time.
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.
