Nitrogen is a component of many biological molecules including
proteins, lipids, nucleic acids, and carbohydrates. Nitrogen is so
important that a shortage of nitrogen will inhibit the growth of an
organism. For example, farmers use nitrogen-based fertilizers to get
the most growth from their crops.
Nitrogen in its elemental form is inert in a human body. But it is
a major component of proteins (amino acids) and nucleic acids which
constitute life. Hence the elemental nitrogen in its compound form is
important for sutaining life!

The atmosphere is 21% oxygen and the rest is almost entirely nitrogen. We as humans would over oxygenate our blood to lethal levels if nitrogen was not present. Our lungs do not absorb the nitrogen, but it keeps the ratio at the desired level
