All organs are important, most are vital. Think about it: could you do without a heart? How dependent are you on your liver? Here is its importance: It weighs around 1.8 kg in men and 1.3 kg in women and holds approximately 13% of your total blood supply - about a pint - at any given time. It actually has over 500 functions.
The liver plays the part of digesting food and helps sort what flows through our bodies in the bloodstream as nutrition to be absorbed or toxis to be excreted. About 60% of the liver is made up of hepatocytes (liver cells) which absorb nutrients and detoxify and remove harmful substances from the blood. Your liver is so vital that you cannot live without it. But advanced surgery has enabled some sufferes to live with only part of their liver.
