Question

Quizplus · Accepted Answer

The intestinal phase is initiated by the entrance of acidic chyme into the duodenum. It involves the release of hormones (such as secretin and cholecystokinin) that inhibit gastric secretion and stimulate the release of pancreatic enzymes and bile from the liver.

Answer: A
 The cephalic phase occurs before food enters the stomach and is initiated by the sight, smell, and taste of food. It involves the release of acetylcholine and other neurotransmitters that stimulate gastric secretion.

Answer: B
 The gastric phase is initiated by the presence of food in the stomach and involves the release of gastrin, which stimulates the production of gastric juice by the gastric glands. This phase is divided into two subphases: the early or neurogenic phase, which is controlled by nerve reflexes, and the later or hormonal phase, which is controlled by the release of gastrin.
