Liver is organ found in your abdominal cavity. Normally you can't feel the liver, because it's protected by the rib cage. The liver has many important functions, including digesting your food and processing and distributing nutrients.Main function of liver is to filter the blood coming from the digestive tract and detoxify any harmful substances or toxins found. When the liver has broken down harmful substances, its by-products are excreted into the bile or blood. Bile by-products enter the intestine and leave the body in the form of feces. Blood by-products are filtered out by the kidneys, and leave the body in the form of urine.

Liver is also responsible for making proteins which are important for blood clotting.

There are many kinds of liver diseases and conditions.  E.g. hepatitis which are caused by viruses. Others can be the result of drugs or alcohol abuse or long-lasting injury or scar tissue in the liver can cause cirrhosis. Jaundice, or yellowing of the skin, can be one sign of liver disease.
