Liver

The liver has many functions, but its main job within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat and some vitamins.

The liver is the body's chemical "factory." It takes the raw materials absorbed by the intestine and makes all the various chemicals the body needs to function.

The liver also detoxifies potentially harmful chemicals. It breaks down and secretes many drugs that can be toxic to the body.

The Digestive Process: The Liver and its Many Functions

The liver is the largest organ in your body. It weighs about 3 pounds and is about the size of a football. It performs many functions essential for good health and a long life.

What the liver does

Your liver works around the clock to keep you healthy. Among its most important jobs are:

· Producing important substances. Your liver continually produces bile. This is a chemical that helps turn fats into energy that your body uses. Bile is necessary for the digestive process. Your liver also creates albumin. This is a blood protein that helps carry hormones, drugs, and fatty acids throughout your body. Your liver also creates most of the substances that help your blood clot after injury.

· Processing bilirubin. The liver helps your body get rid of bilirubin. This happens from the breakdown of your red blood cells. Too much bilirubin in your body can cause jaundice. This is a yellowing of the skin and eyes.

· Removing waste products. When you take in a potentially toxic substance, like alcohol or medicine, your liver helps alter it and remove it from your body.

· Controls immune responses. When bacteria, viruses, and other harmful organisms enter your body, your liver can find and destroy them. This is done by specialized cells in your liver.

· Controlling glucose. The liver helps your body maintain a healthy level of blood sugar. Your liver supplies glucose to your blood when it’s needed. It also removes glucose from your blood when there’s too much.
