3. Alcohol is not digested at all; it is absorbed into your bloodstream directly.
Let’s get technical, shall we? Alcohol is too cool for our body’s normal digestive process. Instead, 20% of the liquor you drink is absorbed directly into the bloodstream from the stomach walls, while the remaining 80% is absorbed through the small intestine. Once absorbed, the alcohol is distributed throughout the body. Being highly soluble in water, it tends to distribute itself in your body’s water tissues. This is the reason that organs containing lots of water, like the brain, are more susceptible to the effects of alcohol.
After which 90% of this alcohol is metabolised by the liver, while the other 10% is expelled from the body through exhalation and incessant trips to the bathroom. Factors such as strength of the drink, your body weight , gender and the speed of drinking determine how fast all that booze will be broken down by your best friend – the liver.(source)
