Question

What are the functions of Bile juices? [3 MARKS]

Answer 1

1. Bile juices emulsify fats and break it down into small particles. This is a detergent-like action of bile which helps the body to absorb the breakdown products of fat 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 juices help in absorption of the fat soluble vitamin.
3. Bile also serves as the route of excretion for bilirubin, a by product of red blood cells.
