The liver is an important organ in the human body. Aside from creating functional molecules and chemicals for the body, it also removes compounds that could possibly poison other organs. Understanding the liver's functions will help prevent liver ailments by learning how to eat better to protect the liver and avoid disease

The Facts
The liver is the biggest organ in the human body. It is found in the right upper section of the abdomen and extends to the top of the diaphragm. The top part is beneath the right lung, the left end is under the heart, the left bottom side is above the stomach, and the right bottom side is above the gall bladder and right kidney and is protected by the right rib cage. Its color is reddish brown and it has a smooth texture. It has four lobes. The liver is larger when the human body is in its infancy stage and reduces in size as the body grows older. It weighs in at 1.2 to 1.5 kg in the female body and 1.3 to 1.6 kg in the male body.

Function:
The liver's function in the human body is to help break down and distribute nutrients in food. Medicine and alcohol are also processed by the liver so that toxins can be removed. The liver produces many chemical compounds that help in various bodily functions, some of which are to help blood to clot, maintain the glucose level in blood by breaking down and transforming glucose into glycogen, and regulating levels of amino acids, the building blocks of protein.

Significance:
The human body cannot function without the liver since it is responsible for many of the processes that the body needs to survive. One major function of the liver is to treat everything that is ingested and produced by the body and turn it into useful chemicals that aid other organs in maintaining the human body's functions. Byproducts that are not needed by the body are turned into waste and excreted.

Considerations
Medications and alcohol have a strong effect on the liver's health. A perfectly functioning liver means that all the organs in the human body will operate just as well. Alcohol abuse and prolonged intake of certain medications change the liver's metabolism and will affect its functions, possibly leading to liver diseases like cirrhosis, hepatitis, liver cancer or Wilson's disease.

Prevention
Drink plenty of fresh water throughout the day to help the liver do its job. Add more fruits and vegetables to your diet and give your liver a rest from red meats and processed food. Eat only fresh food and avoid food that has been reheated more than once. The liver weeds out any bacteria ingested through food intake, and too much harmful bacteria may cause liver damage. Avoid excessive intake of alcohol or avoid it altogether to prevent damage to the liver.
