What is the action of bile on oil?

Bile acts as an emulsifying agent on oil, breaking it down into smaller droplets. This process increases the surface area of the oil, allowing digestive enzymes, such as lipases, to more effectively digest fats. By facilitating the mixing of oil with water in the digestive tract, bile aids in the absorption of fat-soluble vitamins and nutrients. Overall, bile enhances the digestion and absorption of dietary fats.
