"bile duct" 的定义和意义

What is "bile duct"?

The bile duct is a narrow tube that carries bile from the liver and gallbladder to the small intestine. Bile, produced by the liver and stored in the gallbladder, plays a vital role in the digestion and absorption of fats. The bile duct serves as a pathway for the transport of bile, which contains bile acids, cholesterol, bilirubin, and other substances necessary for the breakdown and absorption of dietary fats. It ensures the proper delivery of bile to the small intestine, where it aids in the emulsification and digestion of fats, promoting optimal nutrient absorption.
