Life cannot be imagined without oxygen. But have you ever wondered why we do not breathe any gas other than oxygen? Actually, an American biologist has given the answer to this, which is very interesting. Today we will tell you about it.
Why is breathing important
Breathing is as important for any human being as staying alive. Requires water and food. Actually, breathing also supplies necessary energy to our body, due to which all the organs work. It works like fuel for our body. Let us tell you that without oxygen, mitochondria will not be able to convert it into energy. Apart from this, all living things except some bacteria and some small animals require oxygen.
Oxygen needed
Do you Let us know that there are many ways to take oxygen. Breathing is just one of those ways. When you breathe in, your lungs temporarily hold oxygen. Due to which it passes through the very thin surfaces of your lungs and enters your bloodstream. It is very much needed there.
There is only 21 percent oxygen in the air
There is only 21 percent oxygen in the air, the rest is nitrogen. There is gas. This means that it is necessary to breathe five times to get oxygen equal to the entire lung. Let us tell you that when you breathe, only some oxygen reaches your bloodstream. During this time many cells remain hungry. That’s why we need to breathe again and again. When mitochondria create energy, they expel a kind of smoke, which comes out of our mouth in the form of carbon dioxide. You and I call this process exhalation.
