The liver is a large organ in the right upper part of the abdomen.
It performs a range of complex and important functions that affect all body
systems.
Some of the specific functions of the liver include:
- Controlling the amounts of sugar (glucose),
protein, and fat entering the bloodstream.
- Removing bilirubin,
ammonia, and other toxins from the blood. (Bilirubin is a by-product of the
breakdown of hemoglobin from red blood cells.)
- Processing most of
the nutrients absorbed by the intestines during digestion and converting those
nutrients into forms that can be used by the body. The liver also stores some
nutrients, such as vitamin A, iron, and other minerals.
- Producing
cholesterol, substances that help blood clot, bile, and certain important
proteins, such as albumin.
- Breaking down (metabolizing) many
drugs.
