Bile juice helps in the digestion of food by helping in the digestion of fats. Bile juice contains two major components that are, bilirubin and biliverdin. Bile juice helps in digestion of food as:
1. Breaking down larger fat globules into smaller ones so, that pancreatic enzymes can act on it. This is called emulsification of fats.
2. It decreases the acidic nature of food coming out from the stomach (acidic due HCl) due to its alkaline nature due to, NaHCO3 hence, decreasing the chances of acidity.
3. It helps in the activation of lipase.
