Nitrogen is present in the environment in abundance but still we cant inhale nitrogen

<h3>What is the role of nitrogen in our body?</h3>

Nitrogen is physiologically inert. It contributes nothing to the functioning of our bodies. The cells in our body need oxygen to live, not nitrogen. we can find nitrogen in our body in form of nitrogeneous base in nucleotide.

We inhale all gases present in 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.
