Inhaled and exhaled air

Gas % in inhaled air % in exhaled air
Oxygen 21 16
Carbon dioxide 0.04 4
Nitrogen 79 79
NB These figures are approximate.

### What percentage of nitrogen do we inhale and exhale?

After a human breathes in Earth’s air (roughly 78 percent nitrogen and 21 percent oxygen), he or she exhales a mixture of compounds similar to the air inhaled: 78 percent nitrogen, 16 percent oxygen, 0.09 percent argon, and four percent carbon dioxide.

Do you breathe in and out the same amount of nitrogen?

What we breathe in is far from pure oxygen, but roughly by volume 78 per cent nitrogen, 21 per cent oxygen, 0.965 per cent argon and 0.04 per cent carbon dioxide (plus some helium, water and other gases). When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale.

Why do we inhale and exhale the same amount of nitrogen?

Nitrogen is an inert gas with regard to inhalation / exhalation, that is, the body does not do anything with it. Any inert gas inhaled with X percent by volume will be exhaled with Y percent by volume, with X > Y, because we are exhaling more gas overall than we inhale. We exhale more because of the added water.

## What happens if you inhale too much nitrogen?

Just a few breaths can cause you to exhale most of the oxygen in your system leading to brain death. Nitrogen can be poisonous if you scuba dive and get the bends so badly that the nitrogen bubbles in your blood would cause heart failure. Fast.

### What kind of gases do humans inhale and what do they exhale?

Humans inhale these same gases, though in different proportions to exhalation; that is, oxygen is exchanged for carbon dioxide during breathing. When inhaling, humans take in approximately 21 percent oxygen, 0.04 percent carbon dioxide and 79 percent nitrogen. On exhalation, humans give off approximately 16 percent…

How much oxygen does the human body take in?

When inhaling, humans take in approximately 21 percent oxygen, 0.04 percent carbon dioxide and 79 percent nitrogen. On exhalation, humans give off approximately 16 percent oxygen, 4 percent carbon dioxide and 79 percent nitrogen, according to the BBC; only the amount of nitrogen remains constant in the exchange.

What kind of air does a human Breathe In?

After a human breathes in Earth’s air (roughly 78 percent nitrogen and 21 percent oxygen), he or she exhales a mixture of compounds similar to the air inhaled: 78 percent nitrogen, 16 percent oxygen, 0.09 percent argon, and four percent carbon dioxide.
