About the Liver
Your liver, which is the largest solid organ in your body, plays a vital role in regulating life processes. This complex organ performs many functions essential to life. You cannot live without it.
The liver, located behind the low er ribs on the right side of your abdomen, weighs about three pounds and in the adult, is roughly the size of a football.

Liver Disease in Children
Serious liver disease affects approximately one in every 2,500 children in the United States. Illnesses such as biliary atresia (the most prevalent form of lethal chronic liver disease that strikes infants), acute viral hepatitis and other serious conditions can erode liver function leading to a spectrum of clinical problems ranging from impaired growth and development to death.
Less than 15 years ago, most young children diagnosed with biliary atresia died before the age of two because they were considered too small to receive a liver transplant. Now, infants with this condition are routinely transplanted with high success rates. A major hurdle to overcome has been the scarcity of donors in this age group. This has led to advances in both cadaveric and living donor transplants.
