In liver when metabolism process starts the product which is formed is called as Acetate which is formed by oxidation of acetaldehyde, which is then oxidized to form carbon dioxide (CO2). Even most of the alcohol gets escaped from the liver goes to the blood from which it goes to the heart, skeletal muscles and brain cells.

Excretion of Alcohol From the Body

After the metabolism of alcohol in carbon dioxide and water only 5% of alcohol is excreted from the body through saliva, urine, breathe feces and sweat. The metabolism of the alcohol mostly depends upon the function of the liver if the liver is not healthy than the excretion of alcohol will be less and the toxic substance will get accumulated in the body and will produce harmful effects.
