Main Function Of The Liver?

liver functionThe liver is among the most essential organs in our body. It is a football-sized, meaty organ situated at the back of the lower ribs. Weighing over 3 to 4 pounds, the liver performs several essential functions and without it, your systems will definitely fail to work. The main function of the liver is to encourage homeostasis in the body; it only means that your liver works to maintain your body’s optimal operating level.

Because liver is very important, it is crucial that you keep it in shape. By eating right and living a healthy lifestyle, you will surely have a healthier liver that will keep you guarded and functioning well.

Here are some of the main functions the liver have:

Major Player

The liver is a vital player in the circulatory system’s overall function. It is like a checkpoint, it screens the stuff that enters the body. If the substance is beneficial, it will pass the liver’s “screening test” and will be allowed to circulate all through the rest of the organs. On the other hand, if the substance is considered harmful, the liver will isolate it and flush it out of the body.

Food Break Down

Everything you eat and drink goes through your liver by means of the hepatic vein. Hepatocytes convert carbs, proteins and fats into sugar or glucose. When we eat or drink something, food nutrients are broken down and converted into glycogen, which is stored in the liver. Blood glucose can go very low, and when this happens, the liver releases a little of the stored glycogen into the bloodstream. Aside from synthesizing glucose, this major organ also converts excess carbohydrates and proteins into essential fatty acids and triglycerides.


As stated at the first part of this article, the liver acts as a “checkpoint”. One of the most important tasks of the liver is to serve as a detox center. The liver is similar to a sieve; and it plays a great role in keeping harmful toxins out of the body’s system. The liver can work pretty well as a sieve, but it needs special support from the body owner. Eating antioxidant-rich foods is important to prevent toxic buildup in the liver.


The liver secretes an important enzyme called bile, which is then stored in another organ: the gallbladder. Bile consists of water, organic molecules and electrolytes needed in proper digestion and fat-absorption. Bile secretion is very important because this enzyme plays a key role in excess cholesterol removal.

Energy Production

Since the liver is the one that breaks down food for energy conversion, it is also the one that could provide a quick zap of energy when you need it.

Ward Off Infections

Another function of the liver is that it helps your body fight infections, especially those that occur in the bowel. By mobilizing a part of your macrophage system, or the body’s defense system. Half of the Browicz-Kupffer cells or macrophages in your body are found in the liver. Like a bathroom disinfectant, these cells kill bacteria on contact.
