Bile
Bile is a thick, sticky fluid secreted by the liver via the bile duct into the small intestine where it aids in the emulsification of fats, increases peristalsis and restores putrefaction. It contains sodium glycocholate and sodium taurocholate, cholesterol, biliverain and bilirubin, mucus, fat, lecithin cells and cellular debris.
Normally the ejection of bile only occurs during duodenal digestion. Bile is both an antiseptic and a purgative. The normal adult secretes about 800 to 1,000 milliliters daily.
