Explanation

The liver produces and secretes 250 to 1500 mL of bile per day. The major constituents of bile are bilirubin, biliverdin, bile salts, cholesterol and phospholipids. The bile salts play a very important role in the digestion of fats. The bile salts, which are partly water and partly lipid-soluble, emulsify the fat particles and as a result, the fat- drops acquired a greater surface area.
