What organ eliminates ethyl alcohol?

Answer 1

Once absorbed by the bloodstream (straight from the stomach), the alcohol leaves the body in three ways:

The kidney eliminates 5 percent of alcohol in the urine.

The lungs exhale 5 percent of alcohol, which can be detected by breathalyzer devices.

The liver chemically breaks down the remaining alcohol into acetic acid.

Answer 2

As a rule of thumb, an average person can eliminate 0.5 oz (15 ml) of alcohol per hour. So, it would take approximately one hour to eliminate the alcohol from a 12 oz (355 ml) can of beer.
The BAC increases when the body absorbs alcohol faster than it can eliminate it. So, because the body can only eliminate about one dose of alcohol per hour, drinking several drinks in an hour will increase your BAC much more than having one drink over a period of an hour or more.
