what do we/humans breathe in?​

Sagot :

Answer:

Humans primarily breathe in air, which is a mixture of gases. The main components of the air we breathe are:

• Nitrogen (about 78%)

• Oxygen (about 21%)

• Argon (about 0.93%)

• Carbon dioxide (about 0.04%)

• Trace amounts of other gases such as neon, helium, methane, and krypton

Oxygen is the essential gas for respiration, as it is used by our cells to produce energy.
