Zollinger-Ellison syndrome is a disorder where gastrin-secreting tumors cause excessive stomach acid production. This excessive acid can overwhelm the duodenal lining's ability to neutralize it, leading to the development of duodenal ulcers. Treatment typically involves reducing stomach acid production with medications like proton pump inhibitors.
The intestinal hormone that stimulates mucus secretion by the submucosal duodenal glands is called secretin. Secretin is released in response to acidic chyme entering the duodenum, signaling the pancreas to release bicarbonate-rich fluid to neutralize the acidity and protect the intestinal lining.
Bicarbonate's main role is to help neutralize the very acidic contents coming out of the stomach and into the small intestine. This serves a protective role -- to help protect the lining of the small intestine from being eaten away -- as well as a functional one -- the digestive enzymes at work in the small intestine operate better at a higher pH (less acidic).
Secretin is a hormone that controls the secretions into the duodenum, and also separately, water homeostasis throughout the body. It is produced in the S cells of the duodenum in the crypts of Lieberkühn. Its effect is to regulate the pH of the duodenal contents via the control of gastric acid secretion and buffering with bicarbonate from the centroacinar cells of the pancreas as well as intercalated ducts. It is notable for being the first hormone to be identified. In humans, the secretin peptide is encoded by the SCTgene.
Duodenal is not a sphincter. The other options (esophageal, pyloric, ileocecal) are all sphincters.

About 80% of all ulcers in the digestive tract are duodenal ulcers.

Secretin is a hormone that controls the secretions into the duodenum, and also separately, water homeostasis throughout the body. It is produced in the S cells of the duodenum in the crypts of Lieberkühn.[1] Its effect is to regulate the pH of the duodenal contents via the control of gastric acid secretion and buffering with bicarbonate from the centroacinar cells of the pancreas as well as intercalated ducts. It is notable for being the first hormone to be identified.[2] In humans, the secretin peptide is encoded by the SCT gene
No, there is a 30-40% chance of Down Syndrome when duodenal atresia is diagnosed.
The duodenal loop is a section of the small intestine. It is in this section of the small intestine that chemical digestion begins.
