How does pyloric sphincter knows to open for chyme and when to close?
The pyloric sphincter opens in response to the presence of acidic chyme in the stomach. This triggers hormonal and neural signals that stimulate the sphincter to relax and allow the chyme to pass into the small intestine. Once the chyme has been emptied, feedback mechanisms signal the pyloric sphincter to close to prevent backflow of contents into the stomach.
In human beings the opening of the stomach into the small intestine is called?
The opening of the stomach into the small intestine is called the pyloric sphincter. It regulates the flow of partially digested food from the stomach to the small intestine for further digestion and absorption of nutrients.
What will be the effect of cholinergic agonist on the pyloric sphincter?
A cholinergic agonist will cause the pyloric sphincter to relax, leading to increased gastric emptying. This is because cholinergic stimulation promotes smooth muscle relaxation in the gastrointestinal tract, allowing food to pass through the pyloric sphincter more easily.
What is the structure found after the pyloric sphincter?
The duodenum
Does the pyloric sphincter have a enzyme?

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.
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
What are the two openings at the end of the stomach?
There are two openings in the stomach. The first opening is the esophageal sphincter, and the second is the Pyloric sphincter.
Name of the valve between the esophagus and the stomach?

What is a sphincter in the digestive system?
The pyloric sphincter regulates passage of chymefrom the stomach
What is the most difficult biological molecule to get through the pyloric sphincter?
The pyloric sphincter will allow any molecule, not just biological ones, to go through because molecules are so much smaller than the opening created by the sphincter when it opens up.

Is the ring like muscle that controls the flow from the stomach to the small intestine?
The ring like muscle that controls the flow from the stomach to the small intestine is called the pylorus or the pyloric sphincter. It is divided into two parts: the pyloric antrum which is connected to the body of the stomach and the pyloric canal which is connected to the beginning of the small intestine (the duodenum).
What is the relationship between pyloric sphincter and chyme?
The pyloric sphincter regulates passage of chyme from the stomach.
What is the valve between the stomach and small intestine of a frog?
pyloric sphincter valve pyloric sphincter valve
What is the name of the valve at the end of the esophagus?
A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
Does a frog have a pyloric sphincter?
Yes, The pyloric sphincter valve regulates the exit of digested food from the stomach to the small intestine.
