What air do we breathe out?
When we take a breath, we pull air into our lungs that contains mostly nitrogen and oxygen. When we exhale, we breathe out mostly carbon dioxide.
What causes air to move?

Can humans breathe liquid?
Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid (such as a perfluorocarbon), rather than breathing air. By selecting a liquid that is capable of holding large amounts of oxygen and CO2, gas exchange can occur.
How much water do we breathe out at night?
A person could perspire and exhale 40 g of water vapour per hour when sleeping, 70 g/h when seated and 90 g/h when standing or doing housework.
What makes up 80% of the air we breathe?

What makes up the majority of the air?
By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
Can we breathe on Mars?
Carbon dioxide atmosphere By comparison, Mars’ atmosphere is 95 percent carbon dioxide. “We need to breathe oxygen,” said Lee. “There’s no free oxygen in the Martian atmosphere. You cannot breathe this gas.
How do we feel the presence of air?
