The liver is a very important organ possessed by vertebrates, and some other animals. The liver, which is part of the digestive system, is the largest internal organ of the human body weighing about 3 pounds (1.36 kilograms). It is reddish brown in color. The liver is divided into four lobes, which are of unequal size and shape.
The liver is positioned under the diaphragm, on the right side of the abdominal cavity with its larger mass on its right side and extends just a little bit more to the left from the midline. In other words, if you palpate carefully just under your right costal arch (under your right ribs) and a bit upward you might feel your liver.
Functionally, the human liver executes well over 500 different functions, all of which are indispensable to life. Its necessary functions include assisting the body’s fats digestion, detoxification, storing reserves of nutrients, sifting poisons and wastes from the blood, producing a multiplicity of proteins, modifying the levels of many chemicals present in the bloodstream, and production of bio-chemicals needed for digestion.
The liver is exceptional among all of the body’s vital organs in that it has the ability to rejuvenate, or grow back, cells that have been damaged by some short-term injury or disease. But if the liver is damaged continually in excess, it may experience irreparable alterations that permanently obstruct with function.
The liver is crucial for survival. There is presently no means to compensate for the nonexistence of liver function.
