Functions of bile juice: 1 Mark each
1. Bile juice emulsifies fats and breaks them down into small particles. This is a detergent-like action of bile which helps the body to absorb the broken down fat products in the gut. In connection to this, bile salts bind with lipids to form micelles. This is then absorbed through the intestinal mucosa.
2. Bile juice helps in the absorption of fat-soluble vitamins.
3. Bile also serves as the route of excretion for bilirubin, a by-product formed during the destruction of red blood cells.
