Verified step by step guidance

Identify the function of the gallbladder: The gallbladder stores and concentrates bile produced by the liver, which is released into the duodenum to aid in the digestion of fats.

Understand the role of bile: Bile contains bile salts that emulsify fats, breaking them down into smaller droplets, which increases the surface area for digestive enzymes to act upon.

Recognize the role of hormones in digestion: Different hormones are released in response to food intake and play specific roles in the digestive process.

Focus on the hormone Cholecystokinin (CCK): CCK is released by the small intestine in response to the presence of fats and proteins in the chyme entering the duodenum.

Determine the action of CCK: Cholecystokinin stimulates the gallbladder to contract and release stored bile into the duodenum, facilitating the emulsification and digestion of dietary fats.
