What is Bile?

Bile or gall is a bitter-tasting, dark green to yellowish brown fluid, produced by the liver of most vertebrates, that aids the digestion of lipids in the small intestine. 

In many species, bile is stored in the gallbladder and, when the organism eats, is discharged into the duodenum. Bile is 85% water, 10% bile salts, 3% mucus and pigments, 1% fats, and 0.7% inorganic salts.
