What Your Liver Does


Liver is an important organ in the human body and it has a main role in the metabolism of the body. Being one of the biggest organs of the body it has several other roles to play too. It helps convert nutrients in the diet into other substances that are useful for the body. This organ will also store the substances thus converted and will supply them to the cells when they are in need of them. Another important work is that the liver will take up all the toxic material and then will convert them into harmless substance or will ensure that they are taken out of the body.

Our diet contains various nutrients like proteins, carbohydrates, fats, minerals and vitamins. All these need to be metabolized and then absorbed by the body. It is the liver that plays a major role in the metabolism of these nutrients.

The liver cells will break down the fat and lipids in the nutrients and will help produce energy which is really needed for the body to stay hale and healthy. Bile a yellowish green liquid is produced by the liver cells and then via the bile ducts it is carried to the small intestine. Here the fats are broken down and then their absorption is aided.

The carbohydrates are also metabolized in the liver. The liver makes sure that the sugar level in the blood remains constant. Usually after a meal the blood sugar level is bound to increase. The liver will then remove the sugar from the blood and then stores it by way of glycogen. When the body faces a situation of low blood sugar level this glycogen is broken down and sugar is supplied to the blood.

The liver too stores minerals, vitamins apart from sugar. These are then released into our blood when they are needed.

The liver also helps in protein metabolism . The amino acids in the food are changed by the liver cells these are then used to release energy. These can be also used to make fats or carbohydrates.

During this process ammonia is released as a byproduct. This is toxic and then it is converted into urea by the liver into urea and then released into the blood. This urea is taken to the kidneys and then are released from the body through urine.

Liver will produce some kind of proteins with the help of vitamin K. These proteins will help with the blood clotting. This organ also has a big part to play in the breaking down of the damaged or old blood cells.

The liver tissue is made up of cells that are called lobules. There are several canals that carry blood and bile run between these liver cells. The blood from the digestive organs will flow through portal veins to the liver that carries nutrients, toxic substances and medication. Once these reach the liver they will be processed, altered, stored, detoxified and then passed back into the blood or released into the bowel to be eliminated. This way the liver helps remove toxic and unwanted substances.
