Liver [Description of the Liver]

Functions of the Liver

The liver is one of the largest and most complex organs in the body. It weighs approximately 1,500-1,800 grams (or about three to four pounds) and is made up of a spongy mass of wedge-shaped lobes. The liver has numerous functions that are necessary for life. The liver helps process carbohydrates, fats, and proteins, and stores vitamins. It processes nutrients absorbed from food in the intestines and turns them into materials that the body needs for life. For example, it makes the factors that the blood needs for clotting. It also secretes bile to help digest fats, and breaks down toxic substances in the blood such as drugs and alcohol.

Liver Transplant Procedures

A liver transplant may involve the whole liver, a reduced liver, or a liver segment. Most transplants involve the whole organ but segmental transplants have been performed with increasing frequency in recent years. This would allow two liver recipients to be transplanted from one cadaveric donor or to allow for living donor liver donation. A reduced liver transplant may result if the donor liver is too large for the recipient.
