Description: The bile duct is a tube that transports bile from the liver and gallbladder to the small intestine. This system of ducts is essential for digestion, as bile plays a crucial role in emulsifying fats, facilitating their absorption in the intestine. The bile duct consists of several segments, including the hepatic duct, cystic duct, and common bile duct. The hepatic duct collects bile produced by the liver, while the cystic duct connects to the gallbladder, where bile is stored and concentrated. Finally, the common bile duct transports bile to the small intestine, specifically to the duodenum, where it mixes with digested food. The regulation of bile flow is managed through sphincters, such as the sphincter of Oddi, which opens and closes to allow the passage of bile at the appropriate time. The health of the bile duct is essential, as obstructions or inflammations can lead to serious conditions such as cholecystitis or cholangitis, affecting digestion and nutrient absorption.
