Detailed explanation-1: -Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.
Detailed explanation-2: -Bile juice has bile pigments such as bilirubin and biliverdin. These pigments break down large fat globules into smaller globules so that the pancreatic enzymes can easily act on them. The process is known as emulsification of fats.
Detailed explanation-3: -Bile salts break down larger fat globules in food into small droplets of fat. Smaller fat droplets are easier for the digestive enzymes from the pancreas to process and break down. The bile salts also help the cells in the bowel to absorb these fat droplets.
Detailed explanation-4: -The function of bile salts in the duodenum is to solubilize ingested fat and fat-soluble vitamins, facilitating their digestion and absorption. From the liver, bile flows from the intrahepatic collecting system into the right or left hepatic duct, then into the common hepatic duct.
Detailed explanation-5: -Bile juice has bile salts such as sodium taurocholate and sodium glycocholate. These break down large fat globules into smaller globules and make the small intestine alkaline so that the lipase present in the pancreatic enzymes gets activated and can easily act on them.
