The liver is a vital organ located in the abdomen right above the stomach. It is the heaviest internal organ, weighing an average of 3 lbs. Its job is to regulate the chemical levels in the blood and to excrete bile, ridding the body of waste. The liver has hundreds of important functions including detoxification of the blood, producing cholesterol, producing certain proteins for blood plasma, storing glycogen, and many others.
The liver is a dark red gland that consists of two lobes. It holds about 13% of the body's blood at once, receiving blood from the stomach and intestines, cleaning it out, and passing it through to the rest of the body. The liver supports almost every other organ in the body
Hepatitis is a condition in which the liver tissue is inflamed. The cause is usually viral and includes hepatitis A, B, C, D, and E. Other threats to the liver include excess toxins in the bloodstream, alcohol abuse, and excess drug use (paracetamol among others).
