pyloric sphincter

The pyloric sphincter, at the lower end of the stomach.

As a result, the organ always curves somewhat to the left before curving back to meet the pyloric sphincter.

After being processed in the stomach, food is passed to the small intestine via the pyloric sphincter.

Food from the stomach is allowed into the duodenum through the pylorus by a muscle called the pyloric sphincter.

The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins.

It abuts the Pyloric sphincter.

About 3ml of chyme is squirted into the small intestine at short intervals as the pyloric sphincter opens.

Once processed and digested by the stomach, the milky chyme is squeezed through the pyloric sphincter into the small intestine.

Anatomic localization of cholecystokinin receptors to the pyloric sphincter.

It is near the bottom of the stomach, proximal to the pyloric sphincter, which separates the stomach and the duodenum.

The pylorus of the stomach has a thickened portion of the inner circular layer: the pyloric sphincter.

Foreign bodies most commonly become lodged in the stomach because of the inability to pass through the pyloric sphincter, and in the jejunum.

This acidity is due to hydrochloric acid in the chyme that enters the duodenum from the stomach via the pyloric sphincter.

The small intestine is traditionally divided into three anatomic sections defined from their distance from the pyloric sphincter:

It was known that the pancreas secreted digestive juices in response to the passage of food (chyme) through the pyloric sphincter into the duodenum.

Strengthens antral contractions against the pylorus, and relaxes the pyloric sphincter, which stimulates gastric emptying.

The air is trapped in the stomach and proximal duodenum, which are separated by the pyloric sphincter, creating the appearance of two bubbles visible on x-ray.

Retroperistalsis, starts from the middle of the small intestine and sweeps up digestive tract contents into the stomach, through the relaxed pyloric sphincter.

The effect of this is that gastrin secretion declines and the pyloric sphincter contracts tightly to limit the admission of more chyme into the duodenum.

In pyloric stenosis, it is uncertain whether there is a real congenital narrowing or whether there is a functional hypertrophy of the pyloric sphincter muscle.

Symptoms of duodenal ulcers would initially be relieved by a meal, as the pyloric sphincter closes to concentrate the stomach contents, therefore acid is not reaching the duodenum.

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.

Enterogastric reflex inhibits vagal nuclei, activating sympathetic fibers causing the pyloric sphincter to tighten to prevent more food from entering, and inhibits local reflexes.

They are the esophageal sphincter (found in the cardiac region, not an anatomical sphincter) dividing the tract above, and the pyloric sphincter dividing the stomach from the small intestine.
