Final answer:
The hormone secretin is responsible for c. stimulating the pancreas to release a bicarbonate-rich fluid that aids digestion by neutralizing stomach acid. This hormone is released in response to the presence of acidic chyme.
Step-by-step explanation:
The hormone secretin matches with description 'c) Stimulates release of pancreatic juice' because it is released by the small intestine's duodenum in response to acidic chyme entering from the stomach. When secretin enters the bloodstream, it reaches the pancreas and stimulates it to release a bicarbonate-rich fluid, which helps neutralize stomach acid and supports digestion.
It's important not to confuse secretin with other hormones like gastrin, which stimulates the secretion of gastric acid, or cholecystokinin (CCK), which stimulates the secretion of pancreatic enzymes and bile. While all these hormones interact within the gastrointestinal system, each has specific roles in aiding digestion.
Secretin is a hormone involved in gastric secretion that stimulates the release of pancreatic juice by the pancreas.
Secretin is released by specialized epithelial cells located in the mucosal epithelium of the stomach and small intestine, and it enters the bloodstream to reach its target organs.
When secretin is released, it stimulates the pancreas to secrete a watery secretion of bicarbonate, which helps in neutralizing stomach acid.
