<P> The coordinated action of the forementioned hormones results in the secretion of a large volume of the pancreatic juice, which is alkaline and enzyme - rich, into duodenum . The pancreas also receives autonomic innervation . The blood flow into pancreas is regulated by sympathetic nerve fibers, while parasympathetic neurons stimulate the activity of acinar and centroacinar cells . </P> <P> Pancreatic secretion is an aqueous solution of bicarbonate originating from the duct cells and enzymes originating from the acinar cells . The bicarbonate assists in neutralising the low pH of the chyme coming from the stomach, while the enzymes assist in the breakdown of the proteins, lipids and carbohydrates for further processing and absorption in the intestines . </P> <P> Pancreatic juice is secreted into the duodenom through duodenal papilla . Some individuals have also an accessory duct, named accessory pancreatic duct, which may be functional (that is, it also empties the contents of the exocine pancreas into the duodenum) or non-functional . </P>

Where do the digestive enzymes go that are produced by the pancreas
