[Sidenote: Function of bile]
The bile is a juice secreted by the liver and is alkaline in character.
It is collected by the biliary ducts to be conveyed into the duodenum.
The most important constituents of bile are bile salts and sodium
glycocholate. The chief purposes of bile are to emulsify fats, thus
aiding them to pass through the intestinal walls, and to stimulate
intestinal peristalsis.
