Justification of bile as a digestive Juice

Bile is a secretory product of liver made up of salt, pigment and other substances, dissolved in an alkaline solution which is stored in Gallbladder. It is a sticky fluid produced in the liver, stored in the gallbladder and delivered into the intestine, where it aids in the digestion of fat. The juices secreted from the glands of the digestive tract and help in the digestion of food are called digestive juice. It contains enzymes – substances that speed up chemical reactions in the body—that break food down into dissimilar nutrients.
