secretin

(noun)

A peptide hormone secreted by the duodenum that serves to regulate its acidity.

Examples of secretin in the following topics:

  • Pancreatic Juice

    • Pancreatic juice secretion is regulated by the hormones secretin and cholecystokinin.

  • Intestinal Phase

    • Chyme also stimulates duodenal enteroendocrine cells to release secretin and cholecystokinin.

  • Hormones of the Digestive System

    • Secretin is in the duodenum and signals the secretion of sodium bicarbonate in the pancreas and it stimulates the bile secretion in the liver.

  • Digestive Processes of the Small Intestine

    • The hormone secretin also causes bicarbonate to be released into the small intestine from the pancreas, neutralizing the potentially harmful acid coming from the stomach.

  • Gastrointestinal Reflex Pathways

    • These hormones fall into three major categories: the gastrin family, the secretin family, and a third family composed of the remaining hormones that fit into neither of the these two families.

  • Other Hormone-Producing Structures

    • Secretin - is in the duodenum and signals the secretion of sodium bicarbonate in the pancreas and it stimulates the bile secretion in the liver.

  • Associated Organs

    • The exocrine function of the pancreas is controlled by the hormones gastrin, cholecystokinin, and secretin, which are hormones secreted by cells in the stomach and duodenum in response to food.

  • Digestive Properties of the Stomach

    • In a different and rare manner secretin, which is produced in the small intestine and primarily effects the pancreas, will also diminish acid secretion in the stomach.

  • Absorption of Monosaccharides, Amino Acids, Dipeptides, Tripeptides, Lipids, Electrolytes, Vitamins, and Water

    • 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.
