TR3T Humans usually breathe from sixteen to twenty times each minute. If you analyzed 01 the air you breathe, you would find it is a mixture of different gases. Most of it is *nitrogen about four-fifths. One-fifth is oxygen. There is also a tiny amount of carbon dioxide, a little "water vapor (which gives air its humidity), and some "traces of 05 what are called "rare gases. If you were to put a bag over your nose and mouth to catch the air you breathe out, i図 you would find (1)Some strange changes. There would still be the same amount of nitrogen. There would also be the same traces of rare gases. But there would be much less oxygen and a hundred times more carbon dioxide than in the air you breathe in. 10 There would also be considerably more water vapor. TR33 ,What happens is that each time you breathe, an exchange takes place. You keep Some oxygen; you breathe out much more carbon dioxide and water vapor than you breathed in. 、The reason is that every moment of the day and night your body is using up energy. Your heart uses up energy as it beats. Your muscles use up energy. So 15 does your brain, and so does every other part of you. All this energy is produced by the work of the millions and millions of cells that make up your body. Every one of these cells needs Oxygen in order to do its work. As the cells use up oxygen, they form carbon dioxide, which is a “waste product. So your body carries out these two processes at the same time. You breathe in the m3 20 OXygen that cells need to produce energy. You breathe out the carbon dioxide that is harmful. It sounds so simple. Yet your life depends on these processes happening dav and night without interruption.
