Verified step by step guidance

Begin by understanding the role of the pancreas in digestion. The pancreas produces digestive enzymes that are crucial for breaking down food in the small intestine.

Identify the hormones involved in regulating digestive processes. Secretin, gastrin, insulin, and cholecystokinin (CCK) are all hormones that play roles in digestion.

Focus on cholecystokinin (CCK). This hormone is released by the cells in the small intestine in response to the presence of fats and proteins in the chyme.

Understand the action of CCK. It stimulates the pancreas to release digestive enzymes, aiding in the digestion of fats and proteins.

Recognize the regulatory mechanism: CCK acts as a key regulator for the release of pancreatic digestive secretions, ensuring that enzymes are released when needed for digestion.
