After entering the body, alcohol undergoes a series of metabolic and excretory processes. First, alcohol is absorbed into the bloodstream and metabolized by the liver. Next, let's take a closer look at the "trajectory" of alcohol in the body.
First, when alcohol enters the mouth, it is subjected to the action of salivary enzymes. Although salivary enzymes can't break down alcohol, it slows down the absorption of alcohol and gives the body time to adjust to it.
The alcohol is then absorbed into the bloodstream and then travels through the blood circulation to the liver. In the liver, alcohol undergoes a series of metabolic reactions and is broken down into acetaldehyde and acetic acid. This process requires the consumption of a large amount of energy and nutrients, and has a certain burden on liver function.
The decomposed acetaldehyde and acetic acid then travel to other parts of the body with blood circulation, affecting various organs of the body. For example, acetaldehyde can irritate the mucous membranes of the respiratory tract, causing symptoms such as coughing and chest tightnessAcetic acid interferes with the body's absorption of vitamins and minerals, leading to problems such as malnutrition.
Finally, after metabolism and excretion, alcohol is finally excreted from the body in the form of carbon dioxide and water. Of these, carbon dioxide is excreted through respiration and water is excreted through urine and sweat.
Understanding the "trajectory" of alcohol in the body helps us better understand the harm of alcohol to the body, so as to better protect our health. We should drink alcohol in moderation and avoid the harm to the body caused by excessive drinking.
