. Absorption
http://www.padui.org/images/1pix.gifAlcohol is primarily absorbed through the stomach and the small intestines. It is considered a food because it has calories, but does not need to be digested and proceeds directly into the body through the digestive system. After ingestion it is carried through the blood stream and crosses the blood–brain barrier, at which time impairment begins. A greater amount of ingestion causes greater impairment to the brain, which, in turn, causes a person to have a greater degree of difficulty in functioning.
B. Metabolism/Elimination
http://www.padui.org/images/1pix.gifThe majority of alcohol in the body is eliminated by the liver. Ninety percent is eliminated through the body, while ten percent is eliminated (unchanged) through sweat and urine. Before the liver can process alcohol, a threshold amount is needed and can occur at the rate of one 12 oz. can of beer, one 5 oz. glass of wine, or 1 1/2 oz. shot of whiskey per hour.
C. Brief Overview
Alcohol is a central nervous system depressant.
Alcohol is among the most abused drugs in our society.
Alcohol can be as potent as many other illegal drugs.
Alcohol can cause severe damage to a developing fetus.
People often do not realize that they are becoming dependent on alcohol.
D. Short-term Effects
Reduces sensitivity to pain.
Affects vision in the following ways: narrows the visual field, reduces resistance to glare, interferes with the ability to differentiate intensities of light, and lessens sensitivity to colors.
E. Long-term Effects
Damage to vital organs; including liver, heart and pancreas.
Linked to several medical conditions; including gastro intestinal problems, malnutrition, high blood pressure, and lower resistance to disease. Also linked to several types of cancer; including esophagus, stomach, liver, pancreas and colon.
F. Special Hazards Involving the Driving Task
http://www.padui.org/images/1pix.gifSpecific elements to the hazards of alcohol use and driving are listed in a separate section of the curriculum. However, alcohol impairs one's ability to drive or operate machinery safely.
