The duodenum also regulates the rate of emptying of the stomach via hormonal pathways. Secretin and cholecystokinin are released from cells in the duodenal epithelium in response to acidic and fatty stimuli present there when the pylorus opens and releases gastric chyme into the duodenum for further digestion. These cause the liver and gall bladder to release bile, and the pancreas to release bicarbonate and digestive enzymes such as trypsin, lipase and amylase into the duodenum as they are needed.
The bicarbonate released by the pancreas is to neutralize the hydrochloric acid coming from the stomach.

What is the clinical significance of the sudden shift on pH from the stomach to the small intestines?
The stomach is covered in mucus to protect it from the strong acids used to digest proteins. The duodenum (the very first section of the small intestine) does not have such mucus to protect itself. The pH change is crucial to make sure that the duodenum is not harmed by the strong acids from the stomach.
What is the name of the first portion of the small bowel that connects to the stomach?
The Pylorus (the valve between the stomach and duodenum is the pyloric valve)
Is the volumes of the stomach and duodenum the same?
No. The duodenum is part of the small intestine and connects the small intestine to the stomach.
Are the volumes of the stomach and duodenum equal?
No, the stomach is larger in volume compared to the duodenum. The stomach serves as a temporary storage and mixing chamber for food, whereas the duodenum is the first part of the small intestine where further digestion and absorption take place.
When Chyme moves from the stomach into the?
Duodenum
Which term is not associated with the stomach?
duodenum
What is moved through the pyloric sphincter?
Chyme, which is a mixture of partially digested food and stomach acids, is moved through the pyloric sphincter from the stomach to the small intestine for further digestion and absorption of nutrients.
What is pyloric pump of the stomach?
The pyloric pump of the stomach empties what's inside the stomach into the duodenum. The pump is activated when the stomach distends. The pump is inhibited when there's acid inside the duodenum. The pump is also inhibited if there are substances difficult tot digest inside the duodenum.
What does the term duodenum means?
The duodenum is the first section of the small intestine. The duodenum connects the stomach with the jejunum where digestion continues.
What has the author James Sherren written?
James Sherren has written: 'Lectures on the surgery of the stomach and duodenum' -- subject(s): Surgery, Stomach, Duodenum
Where is chyme expelled from the stomach into?
Chyme is expelled from the stomach into the duodenum. The duodenum is the first section of what will become the small intestine inside most vertebrates.
What the pylorus area in stomach?
It is the opening from the stomach into the duodenum (small intestine).
