When highly acidic chyme enters the duodenum, which hormone stimulates the release of pancreatic secretions that contain very high bicarbonate ion content?

When highly acidic chyme enters the duodenum, it has a pH of less than 3.0.(Gibson &Solomon , 2020). This triggers the release of cholecystokinin (CCK) from the small intestine –( Gibson& amp ; Soloman , 2020 ). CCK is a hormone secreted by enteroendocrine cells in response to fatty acids and proteins coming into contact with intestinal mucosa Gibsong 2021).

When highly acidic chyme enters the duodenum, which hormone stimulates the release of pancreatic secretions that contain very high bicarbonate ion content?

In turn, this stimulates pancreatic secretions that contain very high bicarbonate ion content.( Gibson &Solomon ,2020 ) Bicarbonate ions act to buffer the acidity of chyme entering the duodenum .–( Davis et al., 2018) In addition to releasing bicarbonate ions, CCK also causes an increase in saliva production.–( Jackson ,2020 ) The presence of more saliva helps break down food particles and further neutralizes stomach acid as it moves into the small intestine —–( Gibsob &solomobn 2021)
