Aim: How does Alcohol affect the body?

   I.      Alcohol – Ethanol, a waste product in yeast fermentation of simple sugars in fruits,
           grains, roots, etc.
           A. Intoxication – physical & mental changes produced by drinking alcohol

               1. Beer is not necessarily a more mild alcoholic drink than wine or vodka

            B. Effects on the Body
               1. Irritates the mouth, throat, esophagus, stomach. (From vomit)
               2. Makes the heart work harder. (B/c widens blood vessels)
               3. Makes body lose heat due to widening of blood vessels in skin. (This is why
                   person appears “flushed.”)
               4. Causes the liver to work harder. (Must break down toxic substances)
               5. Causes dehydration, aka a Hangover. (B/c breaking down alcohol requires
                   water & then kidneys produce more urine.)
            C. Effect on the Mind
               1. Depressant – slows down nervous system
               2. Lose Inhibitions (natural limits)
               3. Lose ability to focus eyes, speak clearly, be coordinated
               4. Loses judgment
            D. Blood Alcohol Concentration (BAC)
               Legal limit for DUI = 0.08
               (However, even a BAC of 0.02 can affect your ability to drive, etc.)

            E. Effects of Alcohol at Different Blood Alcohol Concentrations
               1. 0.02 BAC = slowed reaction time/feeling of relaxation, warmth, & well-being
               2. 0.05 BAC = feeling of euphoria, loss of inhibitions, decreased judgment
               3. 0.10 BAC = impaired vision, judgment, reflexes, & coordination/mood swings
   4. 0.15 BAC = seriously affected coordination/blurred vision/severely impaired
       speech/difficulty walking & standing/memory problems/mood swings/violent
       behavior
   5. 0.2 BAC = blackouts/memory loss/stomach irritation/vomiting
   6. 0.25 BAC = loss of consciousness/numbness/dangerously slow breathing
   7. 0.3 BAC = coma
   8. 0.4-0.5 BAC = death from alcohol poisoning
F. Effects of Long-Term Use
   1. Cirrhosis – healthy liver cells are replaced by scar tissue.
           a. 12th leading cause of death in USA
   2. Dementia – decrease in brain function due to cell death from repeated
