In order to neutralize the acidic chyme, a hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution and deliver it to the duodenum. In the lower small intestine, the salts and acids are absorbed and passed back into the bloodstream until they are once again extracted by the liver; this cycle, from the liver to the small intestine and blood and then back to the liver, is called enterohepatic circulation.
