As alcohol builds up in your blood, what occurs?

When alcohol enters the bloodstream, it has a depressant effect on the central nervous system. This leads to a slowing down of brain function and an impairment of motor skills and cognitive abilities. As a result, a person’s reaction times become slower, which can significantly affect their ability to respond quickly in various situations, such as driving.

The other options suggest positive effects of alcohol, which contradicts established research on its impact. Alcohol does not enhance focus or improve judgment; in fact, it often leads to poor decision-making and decreased awareness. Understanding this helps reinforce the importance of responsible drinking and being aware of the effects of alcohol on human behavior and capabilities.
