Class 11 Biology- Role of Liver in the Digestion  Role of Liver in the Digestion The main functions of the liver as an accessory digestive organ within the human digestive system are: The secretion of bile and bile salts : In addition to pancreatic and intestinal secretions, a third secretion that is poured into the duodenum is the  bile .  Bile or gall  is a dark green to yellowish brown fluid and  alkaline in nature , produced by the liver and aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile) and stored and concentrated in the gallbladder (gallbladder bile).
