Final answer:
Blood Alcohol Concentration (BAC) is the measure of alcohol in a person's bloodstream, with a BAC of 0.16-0.25% indicating severe alcohol intoxication. Alcohol metabolism breaks down alcohol in the body, with an average rate of 15 mg/dL per hour. Drinking alcohol excessively can lead to various health risks and physical impairments.
Step-by-step explanation:
Blood Alcohol Concentration (BAC) refers to the percentage of alcohol present in a person's bloodstream. A BAC between 0.16-0.25%, which might be seen after consuming 8-12 drinks within 4 hours, generally indicates severe levels of alcohol intoxication. At such levels, individuals may experience acute intoxication, with significant impairment of motor coordination and decision-making abilities. Alcohol metabolism is the process by which alcohol is broken down in the body, primarily by the liver. The rate of alcohol metabolism can vary among individuals, but on average, it is about 3.3 mmol/L (15 mg/dL) per hour. The metabolism of alcohol is important in determining the duration of intoxication and the time necessary to return to sobriety.
Understanding the impact of various BAC levels on the body is crucial for recognizing the risks associated with excessive alcohol consumption. As BAC increases, so does the risk of harm, both immediate and long-term. Alcohol intoxication can lead to a variety of changes in consciousness and physical impairment; therefore, it is important to drink alcohol in moderation and always within legal limits if drinking is to occur.
