Question

Quizplus · Accepted Answer

Hormones are produced in response to food entering the duodenum from the stomach, so option D is the best choice. The presence of food triggers the release of hormones such as secretin and cholecystokinin, which regulate the release of digestive enzymes and bile from the pancreas and gallbladder respectively, and also help to lower the pH of the digested food. Options A and B are incorrect because hormone production is not related to whether the duodenum is empty or the pH of digested food is too high. Option C is partially correct, but it does not explain when hormones are produced specifically.
