Question

When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of nitrogen?

Answer 1

Breathing:

• The act of ventilating a respiratory surface with air is referred to as breathing.
• Breathing is normally achieved through muscular movements that can be classified as inspiration (intake of breath) and expiration (expulsion of air) (outflow of air).

Functioning during breathing:

• Inhaled air contains $20.94$ percent oxygen, $0.04$ percent carbon dioxide, $79.02$ percent nitrogen, and trace gases.
• Exhaled air contains $16.49$ percent oxygen, $4.49$ percent carbon dioxide, $79.02$ percent nitrogen, and other trace gases.

Nitrogen during breathing:

• Nitrogen is an inert gas
• There is no difference in the nitrogen fraction of inhaled and exhaled air during breathing.
