- Name
- Gastrointestinal hormone
- Also known as
- Gastrointestinal peptide
- Species
- Gastrin, secretin, cholecystokinin, etc.
- Function
- Works with the nervous system to regulate digestive organ function
Basic Information
- To date, more than 20 gastrointestinal hormones have been discovered and identified, exerting different physiological effects, such as gastrin, glucagon, secretin, cholecystokinin, gastrostatin, and motilin. .
- Gastrointestinal hormones and the nervous system together regulate the function of the digestive organs, and their effects mainly have the following aspects.
1. Regulate the secretion of the digestive glands and the movement of the digestive tract A hormone can regulate a variety of gastrointestinal functions, and a gastrointestinal function is also affected by a variety of gastrointestinal hormones.
2. Regulating the release of other hormones Gastric antitumor peptides have a strong effect on stimulating insulin secretion, which has important physiological significance for preventing blood sugar from rising too high and losing it from urine. In addition, somatostatin, pancreatic peptide, and vasoactive intestinal peptide can regulate the release of hormones such as insulin, growth hormone, glucagon and gastrin.
3. Nutritional nutrition refers to the role of some gastrointestinal hormones in promoting the metabolism and growth of gastrointestinal tissues. For example, cholecystokinin released from small intestinal mucosa I cells can promote the growth of pancreatic exocrine tissue.
4. Regulation of appetite hunger hormone, leptin and other gastrointestinal hormones can regulate appetite and blood sugar.
