I read in the lessons that the oxygen in the air is about 20 percent and the nitrogen is about 80 percent. And because we absorb oxygen and release carbon dioxide?
Answer: Four-fifths of the air is nitrogen. In addition to the oxygen in the air, nitrogen also goes into the lungs during the inhalation process of our respiration. But only oxygen has the property of penetrating into the blood. Inert nitrogen is excreted the same way it is exhaled. However, we should not say that we take in oxygen and release nitrogen. Leaving means to be considered as excreting the substance produced in the body. The oxygen we take in oxidizes the nutrients in our body and converts them into water vapor and carbon dioxide along with energy. If this carbon dioxide is present in the body, the acidity will increase and undesirable conditions will arise. So let's leave it at that. We will not let the nitrogen go in and get in the same way. The same comes out.
