Relating to the pylorus: The pyloric opening is surrounded by muscular tissue, from the stomach into the duodenum or the first part of the small intestine.

The pyloric distal aperture of the stomach or abomasum, opens into the duodenum.

The term pyloric is used to mean the pyloric part of the stomach, and the pyloric antrum, canal, opening, or sphincter.

A ring of muscles, the pyloric sphincter, serves as a "gate", closing the opening from the stomach to the intestine. It opens periodically, in order to allow the contents of the stomach to move into the duodenum or small intestine.

A rare disorder of the muscle fibers, like the pylorus, failing to relax: A condition of pyloric achalasia causes food to stay trapped in the stomach withoug any blockage or thickening of a muscle.

The initial portion of the pyloric part of the stomach: The pyloric antrum may temporarily become partially or completely shut off from the remainder of the stomach during digestion.

The dilated natural cavity or hollow of the pyloric part of the stomach, is between the body of the pyloric antrum (antrum pyloricum) stomach and the pyloric canal.

The pyloric antrum is the bulging part of the lower end of the stomach between the body of the stomach and the pyloric canal which is near the bottom of the stomach which separates the stomach and the duodenum (small intestine).

A short canal or opening between the stomach and the small intestine: The pyloric canal primarily consists of muscle which can become too narrow, in some circumstances.

When the pyloric canal becomes too narrow, food and liquids may not be able to pass and this can result in symptoms easily feeling full, odorous belching, or nausea and vomiting.

The first part of the duodenum, as seen in a roentgenogram (X-ray) or by fluoroscopy; duodenal bulb: The duodenal cap is the first widened section of the small intestine that links directly to the stomach.

the compression of the pylorus which is he valve-like opening connecting the stomach to the small intestine: Since Joe was having terrible stomach pains, he went to see Dr. Smart who, after examining him thoroughly, told him that he had a pyloric constriction which had to be operated on immediately.

A pyloric constriction is a prominent fold of mucous membrane at the gastroduodenal junction overlying the pyloric sphincter or the thickening of the circular layer of the gastric musculature (stomach muscle) encircling the gastroduodenal junction (place where the stomach and small intestine meet).

Any of several coiled, tubular, mucus-secreting glands situated in the mucus membrane near the pyloric end of the stomach: The pyloric gland produces protective mucus and significant hormone.

The strong band of muscle between the stomach and the small intestine: The pyloric sphincter is a muscular valve that regulates the flow of substances out of the stomach.

A narrowing of the pylorus, the opening between the stomach and into the small intestine; A condition of pyloric stenosis prevents the normal and usual passage of food from the stomach to the duodenum.
