Detailed explanation-1: -The most important bile pigment, bilirubin, is made when red blood cells are broken down in the liver. Bilirubin is what makes urine yellow and stool brown. Bile salts break down larger fat globules in food into small droplets of fat.

Detailed explanation-2: -Lipase. This enzyme works together with bile, which your liver produces, to break down fat in your diet. If you don’t have enough lipase, your body will have trouble absorbing fat and the important fat-soluble vitamins (A, D, E, K).

Detailed explanation-3: -The liver plays a central role in all metabolic processes in the body. In fat metabolism the liver cells break down fats and produce energy. They also produce about 800 to 1, 000 ml of bile per day.

Detailed explanation-4: -Bile is formed by filtration in response to osmotic gradients created by the transport of osmotically active solutes into the bile canalicular lumen. Water and small solutes enter the biliary space passively via solvent drag (514).
