C. The common hepatic duct carries bile from the liver to the cystic duct and common bile duct
D. The common bile duct carries bile from the liver to the cystic duct and common hepatic duct

Final answer:

The common bile duct does not carry bile from the liver to the cystic duct and common hepatic duct; it is formed by the convergence of these ducts and carries bile to the duodenum. Therefore, the most appropriate correct option is D.

Step-by-step explanation:

The correct flow of bile from the liver to the gallbladder and then to the small intestine involves several specific structures and ducts. Bile is secreted by hepatocytes into bile canaliculi, and then moves further into bile ductules and bile ducts. The right and left hepatic ducts carry bile out of the liver and join to form the common hepatic duct. The common hepatic duct merges with the cystic duct from the gallbladder to become the common bile duct. Bile is then transported to the duodenum of the small intestine through the common bile duct when digestion is needed. The gallbladder stores and concentrates the bile, releasing it into the cystic duct when the small intestine requires it for digestion. Referring to the original question, statement D is incorrect because the common bile duct does not carry bile from the liver to the cystic duct and common hepatic duct. Instead, the common hepatic duct carries bile from the liver to the cystic duct, which then contributes to the formation of the common bile duct.
