What gas do you take in as you inhale?

Answer 1

The air we breathe is roughly one fifth oxygen and four fifths nitrogen.

There are very small percentages of other gases such as Carbon Dioxide, Neon, Helium, Methane, Krypton, Hydrogen and Xenon.

Answer 2

Oxygen is taken in and Carbon dioxide is breathed out during breathing. However, other gases are taken in in very small amounts, for example, Nitrogen. A small amount of Carbon Dioxide is also taken in during breathing.

Answer 3

When you inhale to take gas in. When you exhale you put gas out.

• Inhaled gas contains about 21% oxygen, 78% nitrogen and 1% argon. There are also a few trace gasses of which carbon dioxide at about 400 ppm is the most significant.
  
• Exhaled gas contains less oxygen and more carbon dioxide. There is about 78% nitrogen, 16% oxygen, i% argon and 5% carbon dioxide.
  

In both the above cased the water vapour in the gas mixtures is ignored.

Answer 4

oxygen
