secretin. a hormone secreted by the mucosa of the duodenum and jejunum when acid chyme enters the intestine; carried by the blood, it stimulates the secretion of pancreatic juice and, to a lesser extent, bile and intestinal secretion.secretin test. hormone, formed by the epithelial cells of the duodenum under the stimulus of acid contents from the stomach, which incites secretion of pancreatic juice; used as a diagnostic aid in the diagnosis of pancreatic exocrine disease and as an adjunct in obtaining desquamated pancreatic cells for cytologic examination.
1. Proteases Digestion of proteins is initiated by pepsin in the stomach, but the bulk of protein digestion is due to the pancreatic proteases. Several proteases are synthesized in the pancreas and secreted into the lumen of the small intestine.ancreatic juice is composed of two secretory products critical to proper digestion: digestive enzymes and bicarbonate. The enzymes are synthesized and secreted from the exocrine acinar cells, whereas bicarbonate is secreted from the epithelial cells lining small pancreatic ducts.
