2. Alcohol exists in various kinds of alcohol in different proportions, which can quickly play a role in the human body and change people's mood and behavior. This is because alcohol can be directly diffused into the blood and distributed throughout the body without digestion. The absorption process of alcohol may begin in the mouth. In the stomach, a small amount of alcohol can be directly absorbed by the stomach wall, and in the small intestine, it will be quickly absorbed in large quantities. After alcohol is absorbed into the blood, it flows to various organs with the blood, mainly distributed in the liver and brain.
3. The metabolic process of alcohol in the body is mainly carried out in the liver. After a small amount of alcohol enters the human body, it can be excreted through the lungs or sweat glands immediately. Most alcohol first reacts with alcohol dehydrogenase in the liver to produce acetaldehyde, which is harmful to human body, but it will soon be converted into acetic acid under the action of acetaldehyde dehydrogenase. Acetic acid is the only substance with nutritional value produced after alcohol enters the human body, which can provide the heat needed by the human body. The metabolic rate of alcohol in human body is limited. If you drink too much, alcohol will accumulate in internal organs, especially the liver and brain. When accumulated to a certain extent, there will be symptoms of alcoholism.
If you drink a lot in a short time, the initial alcohol will be like a mild sedative, which will make people excited and reduce the degree of depression. This is because alcohol inhibits the activity of some brain centers, which usually inhibit extremely excited behavior. This stage won't last long. Next, most people will become quiet, depressed and in a trance until they are unconscious. In severe cases, they may even suffocate because the heart is anesthetized or the respiratory center loses its function.
