True or false: Test your knowledge of alcohol and the body.

📚 Quick Study Guide

• ⚖️ Legal Blood Alcohol Content (BAC): In many places, the legal BAC limit for driving is 0.08%. This varies by jurisdiction.
• 🧠 Brain Effects: Alcohol is a depressant that slows down brain function. It affects judgment, coordination, and reaction time.
• liver Function: The liver metabolizes alcohol at a rate of approximately one standard drink per hour. This rate can vary based on individual factors.
• 💧 Dehydration: Alcohol is a diuretic, meaning it increases urine production and can lead to dehydration.
• 🍎 Metabolism Formula: The Widmark formula estimates BAC: $BAC = \frac{A}{W \cdot r} - \beta \cdot t$, where:
  • $A$ = grams of alcohol consumed
  • $W$ = body weight (grams)
  • $r$ = distribution ratio (0.68 for men, 0.55 for women)
  • $\beta$ = alcohol metabolism rate (grams/hour)
  • $t$ = time (hours)
• ❤️ Cardiovascular Impact: Moderate alcohol consumption may have some cardiovascular benefits, but excessive drinking increases the risk of heart disease and stroke.
• 🤰 Pregnancy: No amount of alcohol is considered safe during pregnancy. It can lead to fetal alcohol spectrum disorders (FASDs).
