Detailed explanation-1: -Hormones control the different digestive enzymes that are secreted in the stomach and the intestine during the process of digestion and absorption. For example, the hormone gastrin stimulates stomach acid secretion in response to food intake. The hormone somatostatin stops the release of stomach acid.

Detailed explanation-2: -Gut hormones Ghrelin is produced in the stomach, and its function is to tell the brain that the body has to be fed. It increases appetite. Gastrin is produced in the stomach when it is stretched. It stimulates the release of gastric juice rich in pepsin and hydrochloric acid.

Detailed explanation-3: -The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation. These processes are regulated by neural and hormonal mechanisms.

Detailed explanation-4: -The hormones, ghrelin and motilin, and their receptors are associated with acceleration of gastric emptying and are targets of novel therapy for gastroparesis, e.g., the pentapeptide ghrelin agonist, relamorelin, and the motilide, erythromycin.
