Effects of Alcohol on the Body
Why alcohol is a problem. Have you seen television programs that discuss the effects of heavy drinking? If you have, you know that alcohol can be a serious problem for both the person who drinks too much and his family. Heavy drinking hurts not only the person who drinks, but may cause embarrassment, financial difficulty, and worry for his. family.
Kinds of alcohol. There are two common types of alcohols, ethyl and methyl . Ethyl alcohol is found in liquors, wines, and beers. Methyl alcohol is found in many products for the home and auto. Methyl is extremely poisonous, and any alcohol that contains it is labeled denatured alcohol.
Alcohol in the system. When a person drinks alcohol, it is quickly absorbed by his blood stream. It is first carried to the liver. Here some of it is oxidized and converted to energy. The remainder is carried by the. blood stream throughout the body, where it affects the cells in many ways. Eventually, the liver oxidizes all the alcohol in the blood stream. Then the effects on the body wear off.
Because of the way alcohol is handled by the body, it is classed as a harmful drug. That is, it has harmful effects on the body when it is absorbed by the blood stream.
Alcohol in the brain. Contrary to what many people believe, alcohol is not a stimulant. It is a depressant. It dulls the activity in the brain. It slows reaction time, disrupts thinking, and distorts a person's abil ity to judge his own actions.
The effects of alcohol are progres sive. That is, the greater the quantity one drinks, the greater the effects will be. The illustration on page 142 shows how alcohol affects different parts of the brain. One drink may noticeably affect only judgment. The effects of the next might show up in a few of the areas shown in the illustration. A third might produce embarrassingly obvious effects in all seven areas.
