Answer: The hormones secretin and cholecystokinin act on the pancreas, stomach, and gallbladder.
Explanation:
The duodenum produces two more hormones. Cholecystokinin (CCK), similar to enterogastrone, is released when fat is present in the chyme. CCK promotes the contraction of the gallbladder, which releases bile into the duodenum to help emulsify and digest fat more effectively. The other hormone from the duodenum is secretin. In response to the acidic chyme entering the duodenum, secretin triggers the pancreas to release bicarbonate, thereby neutralizing some of the acid.
