Verified step by step guidance

Identify the function of the gallbladder in the digestive system. The gallbladder stores and concentrates bile, which is produced by the liver.

Understand the role of bile in digestion. Bile contains bile salts that are crucial for the emulsification of fats, breaking them down into smaller droplets to increase the surface area for digestive enzymes to act upon.

Differentiate between the substances listed: Pancreatic juice, Insulin, Gastric acid, and Bile. Recognize that pancreatic juice contains enzymes for digestion, insulin is a hormone for glucose regulation, and gastric acid aids in protein digestion in the stomach.

Focus on the specific function of emulsifying fats. Bile is the only substance among the options that contains bile salts necessary for this process.

Conclude that the substance secreted by the gallbladder to emulsify fats is bile, as it directly relates to the function of breaking down fats in the digestive system.
