Organ and storage of bile:
The liver is the organ that secretes bile. Bile is then stored in the gallbladder until it is needed for digestion.

Function of bile in digestion:
Bile plays an important role in the digestion of food, especially fats. Its function is to emulsify (break down into smaller particles) the fat molecules, making them easier to digest and absorb.

How does bile work?
Bile is made up of bile salts, cholesterol, and bilirubin. Bile salts are the main component that helps to emulsify the fats. They act like detergents, breaking down the large fat droplets into smaller ones. This increases the surface area of the fat, which makes it easier for the enzymes in the small intestine to break them down into fatty acids and glycerol.

Other functions of bile:
In addition to its role in fat digestion, bile also helps to eliminate waste products from the body. Bilirubin, a waste product from the breakdown of red blood cells, is excreted through bile. Bile also contains other substances that help to neutralize stomach acid and protect the small intestine from harmful bacteria.

Conclusion:
In summary, the liver secretes bile, which is stored in the gallbladder until it is needed for digestion. Bile plays an important role in the digestion of fats by emulsifying them and increasing their surface area. Bile also helps to eliminate waste products from the body and protect the small intestine from harmful bacteria.

Bile is secreted by liver. It is stored in gall bladder. Bile is used to digest fats in the food.
