Q

main stimulus for secretin stimulation

A

ACID

Secretin is released from intestinal mucosa into the splanchnic circulation when a higher acid load enters into the duodenum. This leads to increased bicarbonate secretion from the pancreas to help neutralize the acid and allow pancreatic enzymes (which require a more alkaline pH) to function.
