The liver creates bile out of mostly cholesterol, lecithin, salts and pigments. Bile is important for digestion, with the specific purpose of aiding the digestion of fats.
The liver makes bile, which is then stored in the gall bladder. When eating, the bile is secreted into the duodendum helping to break down fats. The emulsification properties in the bile bind with the fat making the fats easily absorbed into the small intestine. Bile also emulsifies with fat soluble vitamins, namely vitamins D, E and A. These vitamins cannot be absorbed without the presence of bile.
When partially digested food reaches the intestine, a concentrated form of bile is released by the gall bladder to help to complete the digestive process. This process entails sorting the good food from the bad food and reabsorbing the salts, vitamins and fats.
Bile carries with it mostly salts that need to be reabsorbed into the body. These salts contain electrolytes which maintain fluid balance. Stomach disorders which cause vomiting of the bitter tasting yellow brown fluid that is bile cause the loss of these electrolytes and an increase in dehydration of the body.
Though very important in the body, bile does not always work as well as it should. High cholesterol forms gall stones in the gall bladder. These stones are painful and require removal, if the condition deteriorates, the gall bladder may require removal altogether. Without the gall bladder, bile will have no place for storage and it will be difficult to digest or synthesize fats.
