What hormones do stomach cells secrete?
Gastrin is a hormone that is produced by ‘G’ cells in the lining of the stomach and upper small intestine. During a meal, gastrin stimulates the stomach to release gastric acid.
What does the gastrin hormone do?
Gastrin helps the pancreas produce enzymes for digestion and helps the liver produce bile. It also stimulates the intestines to help move food through the digestive tract. Sometimes a test for gastrin is done after eating a high-protein diet or after receiving an injection of the digestive hormone secretin into a vein.
What is secreted by the stomach?
The stomach secretes water, electrolytes, hydrochloric acid, and glycoproteins, including mucin, intrinsic factor, and enzymes (Fig. 24.3). Gastric motility and secretion are regulated by neural and humoral mechanisms.
What is secretin and what is its function?
Secretin has 3 main functions: regulation of gastric acid, regulation of pancreatic bicarbonate, and osmoregulation. The major physiological actions of secretin are stimulation of pancreatic fluid and bicarbonate secretion. S cells in the small intestine emit secretin.
