Secretin and cholecystokinin (CCK) are hormones that are secreted from which gastrointestinal (GI) organ?

C
Pancreas
D
Stomach
Verified step by step guidance1
Understand the role of secretin and cholecystokinin (CCK) in the digestive system. These hormones are involved in the regulation of digestive processes.
Identify the primary function of secretin. Secretin is responsible for stimulating the pancreas to release bicarbonate, which neutralizes stomach acid in the small intestine.
Identify the primary function of cholecystokinin (CCK). CCK stimulates the gallbladder to contract and release bile, and it also stimulates the pancreas to release digestive enzymes.
Determine the organ responsible for the secretion of these hormones. Both secretin and CCK are secreted by the enteroendocrine cells located in the mucosa of the small intestine.
Conclude that the small intestine is the gastrointestinal organ responsible for the secretion of both secretin and cholecystokinin (CCK).
