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 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-3: -Fat digestion begins in the stomach. Some of the byproducts of fat digestion can be directly absorbed in the stomach. When the fat enters the small intestine, the gallbladder and pancreas secrete substances to further break down the fat.
Detailed explanation-4: -Role of Bile Acids in Cholesterol Homeostasis Hepatic synthesis of bile acids accounts for the majority of cholesterol breakdown in the body. In humans, roughly 500 mg of cholesterol are converted to bile acids and eliminated in bile every day.
