What Does the Liver Do?

Every time we examine an organ of the human body, its structure and the way it works almost seems like a miracle to us. The liver is no exception. It is the largest gland of the body and, next to the brain, the heaviest organ.

The average human liver weighs about one kilograms. The liver has to be so large because of the work it does. It only manufactures digestive juices, it is also a filter in which all the food received from the intestine (except fat) goes through a chemical process.

It is like a blood-filled sponge which absorbs the food digested in the intestine. What happens to food in the liver is that it is “reconstructed”. the foreign protein is rebuilt to from human protein.


The liver also “detoxifies” food. When the body takes in nicotine and caffeine, the liver transforms these “poisons” into harmless compound. Liver cells also destroy bacilli that may enter the body.

Because the liver is located between the intestine and the heart, it acts as a kind of dam for the liquids we take in. If you drink a large amount of liquid, the liver cells manufacture the digestive fluid known as bile.

(It is sometimes called “gall”). one of the things bile does is emulsify fat. It divides larges fats drops contained in the digested foods into very fine droplets and thus makes it possible for the body to absorb fat.
