Normally, when the acidic chyme is moved into the duodenum it signals the pancreas to secrete bicarbonate-rich juice into the duodenum and duodenal submucosal glands, and to secrete a mucus that is also rich in bicarbonate.
WebThese enzymes are produced by the exocrine acinar cells of the pancreas and include pancreatic amylase, pancreatic lipase, and trypsin. Bicarbonate, a buffer produced and secreted by the epithelial cells lining the pancreatic duct, reduces the acidity of the chyme entering from the stomach into the small intestine. The production of bicarbonate ... Web1. Introduction. The human exocrine pancreas secretes 1-2 liters of pancreatic juice per day. When stimulated, the pancreas secretes alkaline pancreatic juice containing copious amounts of bicarbonate (HCO 3-) (23, 74).HCO 3-plays essential roles in the digestive system.
