Liver

The liver is a vital organ located in the upper right side of the abdomen. It is the largest internal organ and has many important functions in the body.

Functions of the Liver

The liver performs a wide range of functions, including:

1. Metabolism: The liver processes nutrients from food, converting them into energy, and also helps in the storage of nutrients such as vitamins and minerals.
2. Detoxification: The liver helps to remove toxins and waste products from the body, including alcohol and drugs.
3. Production of bile: The liver produces bile, which is important for the digestion and absorption of fats.
4. Storage: The liver stores glucose in the form of glycogen, which can be released into the bloodstream when needed for energy.
5. Regulation of blood clotting: The liver produces proteins that are important for blood clotting.
6. Immune function: The liver plays a role in the body's immune system, helping to fight infections and remove bacteria from the blood.

Common Liver Diseases

There are several common diseases and conditions that can affect the liver, including:

• Hepatitis: Inflammation of the liver, often caused by a viral infection.
• Cirrhosis: Scarring of the liver, usually as a result of long-term damage from conditions such as alcoholism or viral hepatitis.
• Fatty liver disease: Build-up of fat in the liver, often linked to obesity and diabetes.
• Liver cancer: The development of cancerous cells in the liver, which can be primary (originating in the liver) or secondary (resulting from cancer spread from other parts of the body).
