If the pyloric sphincter were to become parlyzed, therefore remaining in the open position, gastric contents would move very quickly through the stomach into the duodenum and intentestinal tract. Under normal conditions, when the stomach is empty, the sphincter relaxes, allowing the first several bites of food to reach the stomach to move on to the intestines for immediate absorption. After these arrive, the sphincter closes and reopens periodically to manage the flow of partially digested food. In the event this were to be stuck open, one would expect to experience a number of problems. Firstly, the feeling of never being full after eating. Secondly, allowing large quantities of under-digested food to reach the intestinal tract would likely cause constipation and therefore dysfunction of the absorption process, eventually leading to intestinal obstruction.

What will be the effect of cholinergic agonist on the pyloric sphincter?
The pyloric sphincter is mediated by excitatory cholinergic vagal fibers, so a cholinergic agonist would constrict the sphincter.
What is the structure found after the pyloric sphincter?
The duodenum
Which hormone will stimulate the opening of the pyloric sphincter?
Gastrin
In the digestive system what part of the body precedes the small intestine?
The answer to the question is the pyloric sphincter. The pyloric sphincter is the part of the digestive system that precedes the small intestine.Ê
What makes the pyloric sphincter open and close?
acidic ph
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 is a sphincter in the digestive system?
The pyloric sphincter regulates passage of chymefrom the stomach
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.
Sphincter controlling the movement of food from the stomach into the duodenum?
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
What is the valve between the stomach and small intestine of a frog?
pyloric sphincter valve pyloric sphincter valve
Pyloric sphincter function?
The function of the pyloric sphincter is that it controls the movement of food from the stomach into the small intestine.
What will be the effect of cholinergic agonist on the pyloric sphincter?
The pyloric sphincter is mediated by excitatory cholinergic vagal fibers, so a cholinergic agonist would constrict the sphincter.
What is the area of the body around the belly button is called?
This is called the pyloric region. A sphincter called the pyloric sphincter is found there.
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.
Where is the pyloric sphincter is located?
duodeum
What is pre-pyloric?
The bottom of the stomach is the pyloric area, with the pyloric sphincter separating the stomach from the duodenum (first portion of the small intestine). The top of the stomach is the cardiac area with the cardiac sphincter. The pre-pyloric area is the area just above the phyloric sphincter where they do biopsies to test for an H-Pylori infection. The pyloric area consists of two parts the pyloric canal and the pyloric antrum.
