The liver is the largest organ in the body. This body organ possesses some unique features that help it to carry out its digestive roles. For example it can grow a portion of its part if it were removed. This process is called regeneration. The ability to regenerate is important to the liver because it has a lot of functions to perform. The liver is sometimes called a multi-system organ because it performs many digestive functions. Some of the main digestive functions of the liver include;

Production of Urea and Bile 

The liver is responsible for separating bile from urea. This role is carried out when filtering toxins. Bile is a substance that consists of water products and cholesterol. Despite being secreted as a byproduct, Bile goes to the intestines where it is used as an excretory and digestive agent. Production of Bile by the liver is done on a constant basis. Before it’s released to the intestines, Bile is stored in the gall bladder for a while. The other substance produced in the liver; Urea is produced from amino acids as a byproduct. Urea is one of the major components of Urine.

Modulation of Blood Sugar Levels

The Liver is helpful in the body when the digestive system absorbs excess glucose. It aids in this situation by converting the extra energy into glycogen. This substance is highly composed of carbohydrates. As a result the liver helps the body to store excess sugar that a person consumes. Glycogen may is converted back to glucose when the body is not absorbing adequate sugar. This is important in that the blood sugar levels are still kept high even during starvation.


The liver plays an important role by filtering toxins. Filtration of toxins by the liver is very important because excess build up of these substances may lead to poisoning of body organs plus the digestive system. The liver helps in breaking down toxins and other harmful substances in the body. The process of filtering out toxins by the Liver may also be called metabolism. Through metabolizing body nutrients and chemicals, the liver gets a chance to interact with the digestive system. For example it metabolizes alcohol though such kind of interaction that it has with the digestive system. The liver filters toxins before they reach blood reach the rest parts of the body. On top of filtering toxins, it takes some useful elements from the blood that it uses to perform some of its other functions. For example, it takes dietary iron to use in converting sugars to either glycogen or glucose depending on body demand.
