Verified step by step guidance

Understand the role of secretin: Secretin is a hormone that plays a crucial role in the digestive process by regulating the pH of the small intestine.

Identify the function of secretin: Secretin stimulates the pancreas to release bicarbonate, which neutralizes stomach acid entering the small intestine.

Recognize the location of secretin release: Secretin is released by the S cells located in the lining of the duodenum, which is the first part of the small intestine.

Differentiate between the structures listed: The thyroid gland, pituitary gland, and pancreas have different functions and do not release secretin.

Conclude that the small intestine is the correct structure: Based on the function and location of secretin release, the small intestine is the structure that releases secretin.
