Liver

The liver is the largest internal organ in the human body and one of the most active. It is located in the upper right part of the abdomen, just below the diaphragm, and performs hundreds of essential tasks that keep the body functioning normally. Blood from the digestive system passes through the liver, where nutrients are processed before being distributed to the rest of the body.

The liver stores glycogen, a form of glucose that can be released when energy is needed, and also stores certain vitamins and minerals. In addition, it produces bile, a digestive fluid that helps break down fats in the small intestine and allows the body to absorb fat-soluble vitamins more efficiently. The liver also acts as a chemical processing center.

It breaks down alcohol, medications and many harmful substances so they can be removed from the body, while converting ammonia into urea, which is later eliminated by the kidneys. It produces important blood proteins, including albumin and several proteins involved in blood clotting.

Unlike most organs, the liver has a remarkable ability to regenerate, meaning it can replace part of its tissue after injury or surgery, although this capacity has limits. A balanced diet, regular physical activity, maintaining a healthy weight, limiting alcohol consumption and protecting against viral hepatitis all help preserve liver health. Blood tests and medical imaging are commonly used to evaluate how well the liver is functioning.
