Final answer:
As the Blood Alcohol Concentration (BAC) increases, the effects of alcohol on the body become more pronounced, leading to decreased reaction time, impaired judgment, and loss of consciousness. Excessive alcohol use during pregnancy can also have negative effects on a developing fetus.
Step-by-step explanation:
As the Blood Alcohol Concentration (BAC) increases, the effects of alcohol on the body become more pronounced. At low BAC levels, such as after two or more alcoholic drinks, individuals may experience feelings of euphoria. However, as the BAC increases, people may feel more sedated, have decreased reaction time and visual acuity, lowered levels of alertness, and reduced behavioral control. Excessive alcohol use can lead to a complete loss of consciousness and difficulty remembering events during intoxication. Additionally, alcohol can have detrimental effects on a developing fetus if consumed during pregnancy.
