The liver is the largest internal organ in the human body and provides a variety of essential functions. Without the liver we would not be able to digest food or get waste products out of our blood stream. One of the best known liver functions is the production of bile, which is used by the body to digest fats. While it is important, this is only one of the more than 500 essential functions of the liver.

Another of the many important functions of the liver is to create and store Glycogen, which is stored by the liver and used by the body as a form of energy to be used by the body when there is not enough Glucose in the blood. The liver does this by removing Glucose from the blood when there are high levels present and converting it into Glycogen. When the Glucose level in the blood is low the liver reverses the process to provide the body with much needed energy.

The liver is essential to the body's metabolism, it helps the body break down food and retrieves and stores vitamins for use by the body. The liver also helps to produce proteins which are also vital to the body. The liver also aids metabolism by helping to transport water to the blood and tissues of the body while getting waste products out of the body.

It is the job of the liver to get toxins such as alcohol or drugs out of the blood stream; it does this by absorbing the toxins and chemically altering them so that they can leave the body through bile. If these or other toxins were not removed from the body then they could result in poisoning.

The liver is able to regenerate and heal itself by repairing or replacing tissue that is damaged, however there are times when the liver is damaged in a way that it cant repair and this can sometimes be life threatening. In the case of life threatening damage to the liver, a liver transplant may be an option and with new techniques the outcome of a liver transplant has significantly improved and patients have a good chance of leading a healthy life post transplant.
