indication.
1.1.1 Alcohol and its Eects on the Human Body
Alcohol is absorbed into the bloodstream from the mouth, throat,
and stomach. Since alcohol is present in the blood, it can be
detected in human breath. Alcohol in the bloodstream cannot
undergo digestion and chemical reactions. Alcohol in the
bloodstream passes through the membrane of the lung air sacs
(alveoli) into the air as the blood ows through the lungs. The
concentration of alcohol in the alveolar air is directly related to the
concentration of alcohol in the blood. As the alveolar air is
exhaled, the breath alcohol analyzer can detect the alcohol in it.
The alcohol concentration in the breath is related to the alcohol
concentration in the blood. Therefore, a person's BAC can be
determined by measuring the alcohol in the breath. The ratio of
breath alcohol to blood alcohol is usually estimated to be 2,100:1.
All in all, 2,100 milliliters (ml) of alveolar air will contain
approximately the same amount of alcohol as 1 ml of blood.
1.1.2 Alcohol is a Chemical Substance
Alcohol is a kind of chemical substance (ethanol or ethanol)
produced by the fermentation of grapes or grains.
