Alcohol enters the fetus readily through the placenta and is eliminated by maternal metabolism. The genetic influence on alcoholism is described as being polygenic,meaning that there is more than one gene influencing the trait. One such region is near the location of the genesfor the ADH enzyme (see “The cardiovascular system,” on page 36). This isespecially interesting because certain alleles, or versions of theADH gene, have been shown to reduce the risk for alcoholism in Chinese andJapanese populations.
What is a Moderate Level of Alcohol Consumption?
Once a neurotransmitter has passed on itsmessage, it is either broken down by an enzyme or reabsorbed by the same neuronthat released it. Alcohol’s effects are influenced by gender, body weight, and bodytype. Scientific research with animals has contributed to many important advances inscientific and medical knowledge.
Administration of Alcoholic Beverages
However, tolerance varies considerably between individuals, as does individual response to a given dosage; the effects of alcohol differ widely between people. Hence in this context, BAC percentages are just estimates used for illustrative purposes. If your BAC reaches 0.08, it will be back to zero in about five to six hours as you’re sobering up. Once consumed, alcohol is quickly absorbed into the bloodstream, which does the job of transporting it throughout the body.
Once alcohol is in the bloodstream, it can only be eliminated by the enzyme alcohol dehydrogenase, sweat, urine, and breath. Coffee, energy drinks, and a cold shower will not sober you up faster. These might make you feel more awake, but caffeine and cold showers will not how long does alcohol stay in your system pull alcohol out of the blood – and thus will not lower your BAC level.
