The intestinal hormone responsible for stimulating the pancreas to secrete fluid into the duodenum is
a. secretin. c. gastrin.
b. chyme. d. pepsin.
A
The entry of chyme into the duodenum stimulates the production of secretin, which in turn stimulates the pancreas to secrete a highly alkaline fluid into the duodenum. In the small intestine, the chyme mixes with pancreatic enzymes, intestinal enzymes, and bile from the liver and gallbladder and is then reduced to absorbable elements of proteins, fats, and carbohydrates. The nutrients are absorbed through the villi and transported to the liver via the portal system for further processing.
