Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Secretin stimulates the secretion of bicarbonate-rich pancreatic fluid. [11] Secretin enters the intestinal lumen and stimulates bicarbonate secretion, ultimately neutralizing gastric H+, which plays an essential role in fat digestion by creating a more neutral (pH 6 to 8) environment.
