【✔】Nitrogen may take up a large proportion of the air we breathe in but it is extremely inert when we breathe in which is in the form of N2. This means that it doesn't react or bond with any substances in our body so you could say that it's "useless".Basically when air fills our alveoli, by the process of diffusion, only oxygen in the air is taken into the blood stream while the other gases along with the waste CO2 is exhaled. So you do breathe in nitrogen, but it is exhaled as it is by the body
