Verified step by step guidance

Understand the role of the small intestine in the digestive system. It is responsible for the final stages of digestion and absorption of nutrients.

Learn about the hormones secretin and cholecystokinin (CCK). Secretin is released in response to acidic chyme entering the small intestine from the stomach, while CCK is released in response to fats and proteins.

Recognize that secretin stimulates the pancreas to release bicarbonate to neutralize stomach acid, and CCK stimulates the gallbladder to release bile and the pancreas to release digestive enzymes.

Identify the small intestine as the organ that detects the presence of acidic chyme and nutrients, triggering the release of these hormones to aid in digestion.

Conclude that the small intestine is the correct answer, as it releases both secretin and cholecystokinin in response to specific stimuli during digestion.
