Bile contains no digestive enzymes, yet it plays an important role in fat digestion. It intensifies the 'mixing contractions' of intestinal wall. The organic salts by bile reduce the surface tension of fats globules and suspend them in water of digestive juice. It is emulsification of fats. It facilitates easy action of pancreatic juice on fats. They also help in formation of micelles which help to transport of all and products of fat digestion from intestinal lumen to absorptive cells. The inorganic bile salts import alkalinity to chyme and inactivate gastric pepsin.
