Definition: The liver is an important organ of the body that is responsible for detoxification, metabolism, synthesis and storage of various substances.
It's the largest internal organ in the body (the skin is considered the largest organ in the entire body) and it weighs about 3 pounds (1500g). It's located just under the ribs in the right upper part of the abdomen. Most of the liver is protected by the rib cage, but it is possible for doctors to feel the edge of it by pressing deep into the abdomen when the patient inhales a big breath of air.
The liver is crucial to life. Without it, a person couldn't live more than 24 hours. For more information, read Why Is The Liver So Important?
