Bile juice. Bile is a bitter-tasting, dark green to yellowish brown fluid, produced by the liver , it is stored in the gallbladder and upon eating is discharged into the duodenum. . The principal function of the gallbladder is to serve as a storage reservoir for bile. Bile salts act as emulsifying agents in the digestion and absorption of fats Bile is a digestive juice secreted by the liver. Although it does not contain any digestive enzymes, it plays an important role in the digestion of fats. Bile juice has bile salts such as bilirubin and biliverdin. These break down large fat globules into smaller globules so that the pancreatic enzymes can easily act on them
Answer: Three major digestive juices are secreted within the small intestine, they are bile juice, pancreatic juice and intestinal juice. Bile juice helps to break down the lipid molecules into di-and monoglycerides by the lipase enzymes and they are secreted by the liver. The pancreatic juices are secreted by the pancreas Class 7 Biology Nutrition in Animals: Small intestine: Small intestine. Small intestine is the longest part of alimentary canal which is highly coiled and about 7.5 metres long. It secrets intestinal juice. It also receives bile juice from liver and pancreatic juice from pancreas. Functions of small intestine Bile is a digestive juice that is secreted by the liver and stored in the gallbladder. Excess substances that the body does not need, byproducts like bilirubin and wastes processed by the liver are passed out through the bile.
