Alcohol is a depressant. It may give you a feeling of euphoria and aroused senses due to a lessening of inhibitions during the early stages of alcohol intoxication. It depresses the central nervous system—leading to slowed reactions, slurred speech and unconsciousness. Alcohol is oxidized or burned by the liver. The liver can oxidize about one ounce of alcohol an hour-the rest remains to be picked by the blood cells and brought to the brain. Instead of picking up oxygen or other elements, blood transports alcohol to the brain. Alcohol is quickly absorbed into the bloodstream from bowel and less quickly from the stomach and colonin the stomach to be disposed of by the body. About 20 percent goes right through the walls of the stomach and intestines and into the bloodstream. The rest of it stays Alcohol have bad affects on different brain areas. Alcohol first affects the part of the brain that controls inhibitions. When people lose their inhibitions, they may talk more, get rowdy, impetuous and do absurd things. After several drinks, they may feel well but really, their nervous system is slowing down. Alcohol also affects those areas of the brain that control motor coordination and judgment.
The blood alcohol concentration depends on: • the amount consumed in a given time; • the drinker's size, sex, body build and metabolism; • the type and amount of food in the stomach.
When the alcohol comes into the blood, nevertheless, no food or beverage can have such effects. Fruit sugar in some cases can shorten the duration of alcohol's effect by speeding up its elimination from the blood.
The rate of metabolism in the average adult, is about 8.5 g of alcohol per hour. This rate can vary dramatically among individuals, depending on such diverse factors as usual amount of drinking, physique, sex, liver size and genetic factors.
