Detailed explanation-1: -Bile is a physiological aqueous solution produced and secreted by the liver. It consists mainly of bile salts, phospholipids, cholesterol, conjugated bilirubin, electrolytes, and water [1]. Bile travels through the liver in a series of ducts, eventually exiting through the common hepatic duct.

Detailed explanation-2: -Bile enters the duodenum emulsifying fats into smaller globules, which can then be broken down further by lipase enzymes.

Detailed explanation-3: -The emulsifier found in the liver and used in the digestive tract is bile. Bile functions specifically to assist in digesting fat (lipids), where the action of emulsification breaks down the fat into smaller droplets.

Detailed explanation-4: -Their amphipathic nature enables bile acids to carry out two important functions: Emulsification of lipid aggregates: Bile acids have detergent action on particles of dietary fat which causes fat globules to break down or be emulsified into minute, microscopic droplets.

Detailed explanation-5: -Emulsification has done by the action of bile secretes from the liver. Bile contains bile pigment and bile salts. Bile salts break down the fats into smaller globules and result in milky emulsion. These emulsified fats are again digested by pancreatic lipase into fatty acid and glycerol.
