Liver Functions

The liver functions to produce and store proteins, carbohydrates, lipids, and vitamins. The liver has a two-fold function: to produce bile acids to breakdown of dietary fat and synthesis vitamins. Blood carries many proteins, including amino acids, fats, carbohydrates, lipids, and vitamins throughout the body. However, most of these nutrients are not carried through the blood system; they are stored in the liver for use when needed.

So the liver is responsible for production of bile acids, processing toxins in the organ, purification of blood, storage of energy or glucose and detoxification. Bile acids are produced by bacteria in the liver. The liver is also tasked with processing various toxins such as heavy metals, drugs and chemicals. Bile acids transport fat and cholesterol from the gastrointestinal tract to the intestines, where they are used for energy production. The last two functions of the liver are involved in the detoxification of drugs and chemicals.

The major function of the liver is its production of bile production. Bile is an essential substance for the normal digestion of fats. There are two main types of tissues in the liver: parathyroid glands or the sclerocytes, which manufacture bile; and white blood cells, which destroy foreign bodies and promote the absorption of vitamins and minerals in the blood. Besides these two functions, the liver produces other important compounds, called complementarines, that are involved in immunity, the synthesis of vitamin D, protein synthesis, and fatty acid synthesis.

The liver synthesizes protein, is involved in the breakdown of amino acids, produces energy from the food we eat, stores glycogen (a sugar), and utilizes oxygen as fuel. The most important functions of the liver are detoxification of toxins, production of bile, absorption of vitamins, and utilization of protein. Liver is the major detoxification organ in the body. Liver helps in the removal of thousands of harmful toxins everyday.

Bile production is a very important process. It provides nutrients to the bloodstream. Metabolism of carbohydrates, fats, and proteins takes place in the liver. Bile moves from the liver to the intestines and then it returns to the bloodstream. Bile salts form into droplets and forms liquid in the intestine.

The hepatic portal vein absorbs amino acids and glucose from the bloodstream. In the course of metabolism, proteins are broken down into different compounds like amino acids, fats and glucose. These components are then transported through blood to different parts of the body, mainly to the muscles, tissues, organs and brain. The liver plays an important role in our body; therefore, if the liver is damaged due to many reasons, the function of the human body will be greatly affected.

There are several types of liver diseases or conditions. Two of the most common liver diseases are alcoholic hepatitis and fatty liver. Alcoholic hepatitis is a disease process caused by excessive or extensive alcohol consumption. It is damage to the liver cells that results from alcohol consumption. Fatty liver is a disease process resulting from excessive accumulation of fats in the liver cells. This accumulation usually results from excessive or extensive alcohol consumption.

Liver function tests, sometimes called a liver biopsy, are a series of blood tests which give information about the condition of a patient’s liver. These tests consist of high-resolution magnetic resonance imaging, chemistries, transcutaneous Doppler flow, amino acid oxidation rate, triacylglycerol content, bile acid levels, and others. Some of these tests may be done in the blood before or after a liver biopsy is performed. Others can only be done upon request of the patient. The more common tests included in a liver biopsy include a CT scan, an MRI, a liver biopsy, an ultrasound, or a blood test.
