What triggers the release of secretin from the small intestine?

Secretin is a hormone released by the small intestine. Like insulin, the presence of food in the stomach triggers it to release secretin which in turn triggers the pancreas and liver to release bile and pancreatic juice for food breakdown and absorption.

What stimulates the hormone cholecystokinin from the intestinal wall?
This is a digestive hormone released with secretin when food from the stomach reaches the first part of the small intestine. It is made by some of the cells lining the first part of the small intestine.
How are chief cells activated?
Gastric chief cells (as opposed to the chief cells present in the parathyroid gland) are the zymogen cells in the stomach that release pepsinogen (a precursor (zymogen) of pepsin). Without stimulation chief cells normally secrete pepsinogen at about 20% of the maximum ability. ACh (released by nerves) is the most important pathway for gastric chief cell activation. ACh also stimulates parietal cells, which secrete HCl (stomach acid). The fall in pH causes a reflex which further stimulates chief cells. Alternatively, acid in the duodenum (the first portion of the small intestine), stimulates release of secretin from S cells of the small and large intestine. Secretin also activates gastric chief cells.
What substance controls the release of bile into the small intestine?
Cholecystokinin. It targets the gallbladder causing it to release bile into the small intestines.
Which comes first on the grasshopper the small intestine or large intestine?
Food enters the small intestine first. It enters the duodenum in the small intestine.
What describes the ileum of the small intestine?
The ileum of the small intestine is directly attached to the large intestine. It forms the majority of the small intestine. It is C-shaped and short. It is the middle portion of the small intestine. It is at the beginning of the small intestine.
Secretin and cholecystokinin are hormones produced in the?
Small intestine
The hormone secretin responds to food entering the small intestine and stimulates the pancreas to release what?
Bicarbonate.
What is the target organ for hormone secretin?
the stomach, pancreas, small intestine and gallbladder
How do the intestines work?
The small intestine is where most chemical digestion takes place. Most of the digestive enzymes that act in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct. The enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in the small intestine in response to the presence of nutrients. The hormone secretin also causes bicarbonate to be released into the small intestine from the pancreas in order to neutralize the potentially harmful acid coming from the stomach.
What hormone causes an increased output of enzyme-rich pancreatic juice and stimulates gallbladder contraction to release bile?
Bilirubin is used by the liver, to make bile
Protein and fat in your meal signal cholecystokin?
Particularly Fats, they are slow to digest and CCK (cholecystokin) triggers the release of enterogastrone which inhibits peristalsis in the stomach and slows entry of food into the small intestine
What is the Pathway of bile from gallbladder to duodenum?
Liver -> right and left hepatic ducts -> common hepatic duct -> cystic duct -> gall bladder.
What type of food in the small intestine signals the release of bile?
Fat will trigger the release of bile from the gallbladder. The bile is created in the liver and placed in the gallbladder for later use.

Do the stomach release its contents into the small intestine all at once?
Figure it out.lol this guy above me is a dickhere :No, the stomach doesn't release its contents into the small intestine suddenly and all at once. After being in the stomach, food enters the duodenum, the first part of the small intestine.
