Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. Many waste products, including bilirubin, are eliminated from the body by secretion into bileand elimination in feces.
A biliary obstruction is a blockage of the bile ducts. The bile ductscarry bile from the liver and gallbladder through the pancreas to the small intestine (the duodenum). Bile is a dark-green or yellowish-brown fluid secreted by the liver to digest fats.
