Intrahepatic bile ducts are a network of small channels within the liver that transport bile from liver cells to the extrahepatic bile ducts, eventually leading to the gallbladder and small intestine. They play a crucial role in the digestion and absorption of fats by facilitating the excretion of bile, which contains bile acids essential for emulsifying dietary fats.

Liver cells

The extrahepatic bile ducts are a network of ducts that transport bile from the liver and gallbladder to the duodenum, playing a critical role in digestion and the excretion of waste products. Any obstruction or disease affecting these ducts, such as choledocholithiasis or cholangiocarcinoma, can lead to significant clinical consequences including jaundice and biliary cirrhosis.

Extrahepatic Bile Ducts

The gallbladder is a small, pear-shaped organ located beneath the liver that stores bile produced by the liver, releasing it into the small intestine to aid in the digestion of fats. Disorders of the gallbladder, such as gallstones and cholecystitis, can lead to significant pain and may require surgical intervention, often through a procedure known as cholecystectomy.

Gallbladder

The small intestine is a crucial component of the digestive system, responsible for the majority of nutrient absorption and digestion. It is divided into three segments: the duodenum, jejunum, and ileum, each playing a unique role in breaking down food and absorbing nutrients into the bloodstream.

Bile acids are critical for the digestion and absorption of fats and fat-soluble vitamins in the small intestine, and they also play a significant role in regulating cholesterol levels and maintaining liver health. They are synthesized from cholesterol in the liver and can influence metabolic processes, immune function, and gut microbiota composition.
