Do we breathe o2

I'm hoping to get some help from other forum users on this topic. Do we really breathe o2? I'm curious to know what is really going on in our bodies when we take a breath. Is the o2 we breathe providing energy and oxygen for our bodies, or does it just pass through us without having any effect? Does the amount of oxygen we take in depend on the air quality, or is it the same no matter where you are? I'm looking for some advice on understanding the specifics of how o2 works in our bodies and how it affects us.

The air that we breathe is made up of a number of different gases, the most abundant of which is oxygen (O2). Oxygen is essential for all living things, including humans, and makes up 21% of the air we breathe. The other gases include nitrogen (N2), carbon dioxide (CO2), and other trace gases.

Oxygen (O2)

Oxygen is the most important gas that we breathe. It is essential for all life, and makes up 21% of the air we breathe. Oxygen is used in the body to create energy, and is used to help the body to function properly. Without oxygen, the body would not be able to function.

Nitrogen (N2)

Nitrogen is the second most abundant gas in the air we breathe. It makes up 78% of the air we breathe. Nitrogen is essential for the body to function properly, and helps to regulate the body’s pH balance.

Carbon dioxide (CO2)

Carbon dioxide is a trace gas in the air we breathe. It makes up just 0.04% of the air we breathe. Carbon dioxide is essential for the body to produce energy, and is used to help the body to regulate its temperature.

Other Trace Gases

There are a number of other trace gases in the air we breathe, such as argon, helium, and water vapor. These trace gases make up a small percentage of the air we breathe, but are still essential for the body to function properly.
