Bile is a fluid that is made and released by the liver and stored in the gallbladder. The Bile breaks down fats into fatty acids, which can be taken into the body by the digestive tract. It contains mostly cholesterol, bile acids, and bilirubin.

                           Bile plays a vital role in the digestion of fats. It is formed in the liver, where it is principally composed of cholesterol, lecithin, pigments, and salts. Most of the salts in this liquid are reabsorbed back into the body, and are necessary electrolytes. People get severe stomach flus for instance, they may begin to vomit, once their stomachs are empty that is principally made up of this fluid. This means electrolytes are being lost  and people may require electrolyte fluids to restore a healthy balance and prevent dehydration.
