The smooth muscle of the duodenum, which is a part of the small intestine, aids peristaltic contractions, which propel chyme from the stomach for digestion and nutrient absorption. These coordinated muscle movements aid in the mixing of digestive enzymes and bile, which is necessary for effective digestion and nutrient absorption in the early stages of the digestive process.Motilin is a peptide hormone that regulates the migrating motor complex (MMC) in the gastrointestinal tract.Motilin binds to receptors on duodenum smooth muscle cells, causing them to contract. This contraction aids in the movement of food through the digestive tract.Motilin also stimulates the release of other digestive hormones such as gastrin and secretin.Therefore, the correct option is d) motilinGastrin: Stimulates stomach acid secretion and gastric motility.Cholecystokinin (CCK) : Stimulates gallbladder contractionSecretin: Stimulates pancreatic bicarbonate secretion and inhibits gastric acid secretionGastric inhibitory peptide (GIP) : Inhibits gastric acid secretion and slows gastric emptying.The smooth muscle of the duodenum is a target of motilin.
