Verified step by step guidance

Step 1: Understand the function of bile in the digestive system. Bile is a substance produced by the liver and stored in the gallbladder. It helps emulsify fats in the small intestine, specifically in the duodenum.

Step 2: Identify the structures involved in bile transport. The gallbladder stores bile, and bile is transported to the duodenum through a series of ducts: the cystic duct, hepatic duct, and common bile duct.

Step 3: Clarify the roles of each duct. The cystic duct connects the gallbladder to the common bile duct, allowing bile to flow from the gallbladder. The hepatic duct carries bile from the liver. The common bile duct is formed by the union of the cystic duct and hepatic duct, and it delivers bile directly to the duodenum.

Step 4: Eliminate incorrect options. The pancreatic duct is not involved in bile transport; it carries pancreatic enzymes to the duodenum. The hepatic duct only carries bile from the liver, not from the gallbladder. The cystic duct connects the gallbladder but does not directly transport bile to the duodenum.

Step 5: Conclude that the common bile duct is the correct structure that carries bile from the gallbladder to the duodenum, as it is the final pathway for bile delivery to the digestive system.
