The liver plays an important role in the food digestion. The liver secretes bile juice which helps in the digestion of the fats. In the absence of digestion, this bile is stored in the gall bladder. The bile juice is the yellowish fluid, which aids in the digestion of fats (occurring in the small intestine) by emulsifying the fats molecules. the emulsification of these fat molecules is critical for their digestion, and absorption. Hence, the liver secretes bile juice and acts to emulsify the fat in the lumen of the small intestine.
