The liver is the largest organ in the body after the skin and acts as the gatekeeper of your body. Everything that happens and is digested in the body goes through the liver (liver) which has evolved to handle our organic waste. Because of its size, the liver (liver) that is attached to two very large blood vessels keeps whatever enters through the intestinal tract, and unwanted objects out. This includes toxins or environmental carcinogens. These 'bad' substances are prevented from getting into the bloodstream.
