THE BREATHED IN AIR IS NOW IN THE LUNGS

The air that comes to the lungs is ready for use as it has been cleaned and its humidity has been regulated through the windpipe. By means of blood circulation from the lungs, it is conveyed to all cells of the body to nourish them. In the meantime it receives from the cells carbon dioxide, which is a waste material. When we expel breath, we give out this carbon dioxide that is collected from our cells. You may consider breathing a simple process, but a significant exchange of oxygen and carbon dioxide takes place deep inside your body. All these are Allah's gifts to us; He created all of them and placed them at our service. Consider how it would be even if merely respiration were under our conscious control. We would not be able to faultlessly carry out this process. We would get tired and would eventually give up after some time. Our Lord knows that we cannot perform this task on our own. So He created the respiratory system which runs perfectly like all other systems as we have explained throughout the book. This is one of the gifts that Allah has given us in this world. As stated in a verse:
He has given you everything you have asked Him for. If you tried to number Allah’s blessings, you could never count them. Man is indeed wrongdoing and ungrateful. (Surah Ibrahim: 34)
