Because air is composed of nitrogen (not 100% mind you) and when you exhale air, you also exhale nitrogen.
Over 99 percent of the atmosphere in pure dry air is composed of nitrogen and oxygen, with nitrogen making up about 78 percent and oxygen around 21 percent. The remaining 1 percent is made up of trace gases such as argon, carbon dioxide, and neon.
