The alcohol contained in your drink is absorbed by your body through your stomach and small intestines. Food reduces the absorption time and that's why alcohol affects you faster when you drink on an empty stomach.
Alcohol is transferred to the liver from the small intestine and then to the heart, brain, muscles, and other tissues. This is happening very quickly, in a matter of minutes. Usually, though not always, this has a pleasant feel.
Our body can't store alcohol, so it breaks it down. That is the job of your liver. Initially, the liver converts alcohol into acetaldehyde (toxic), then into acid (harmless), which is then separated into carbon dioxide and water. Approximately 90% - 95% of the alcohol you consume is broken down by the liver, while 5% - 10% is eliminated through urine, breath, and sweat.
Your body's ability to process alcohol depends on your age, weight, and gender. Your body breaks down alcohol at the rate of one unit of alcohol every hour and a half, and there is no way to accelerate this process.
