The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration.
So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
What else can I help you with?
Is the atmosphere on Venus mostly Methane?
No. The atmosphere of Venus is mostly carbon dioxide with some nitrogen and trace amounts of other gasses.
What is The invisible mixture of gases you breathe?
The invisible mixture of gases you breathe is called air. It consists mostly of nitrogen (about 78%) and oxygen (about 21%), with small amounts of other gases like carbon dioxide and argon. These gases are essential for life and play a crucial role in maintaining the Earth's atmosphere.
What is the atmosphere on mars composed mostly by?
The atmosphere on Mars is composed mostly of carbon dioxide (about 95.32%), with traces of nitrogen (2.6%) and argon (1.9%). There are also small amounts of oxygen, carbon monoxide, methane, and water vapor.
Is Venus made mostly out of rock and gas?
Venus is made up of an iron core and rocky mantle. While it's atmosphere mostly consists of carbon dioxide and nitrogen.
What are the major gases on Mars?
The major gases in the atmosphere of Mars are carbon dioxide, nitrogen, and argon. Carbon dioxide makes up about 95% of the Martian atmosphere, with nitrogen and argon making up most of the remaining percentage. There are also trace amounts of other gases such as oxygen and water vapor.
Do you breathe mostly carbon dioxide?
No, air is mostly nitrogen and oxygen with very very little carbon dioxide (less than 1%)What you exhale is mostly nitrogen, oxygen, and some carbon dioxide.
Why cant you breathe on Venus?
It's mostly carbon dioxide and a little nitrogen. We need oxygen and a lot of nitrogen.
What is air you breathe made up of?
I think mostly oxygen, and some nitrogen. Also, some carbon dioxide.
Do humans breathe nitrogen as a part of the air they inhale?
No, humans do not breathe in nitrogen as a part of the air they inhale. The air we breathe is mostly made up of oxygen, with a small amount of other gases like nitrogen and carbon dioxide.
Is the air we breath is mostly nitrogen?
Yes, the air we breathe is mostly nitrogen, with about 78% of the atmosphere made up of nitrogen. Oxygen makes up about 21% of the air, with trace amounts of other gases such as carbon dioxide, argon, and others.
What do humans breathe in?
The air we breathe is mostly made up of nitrogen and oxygen. The remaining 1% is made up of argon, carbon dioxide and other trace gases. Even water vapor (water in its gaseous state) is present in air in varying amounts.
What do you breathe in and out?
You breathe in air, which is comprised mostly of nitrogen (though the oxygen is what you're after).The oxygen is absorbed into the blood, and stored in red blood cells, which contain hemoglobin.The oxygen in your lungs is thus replaced mainly by carbon dioxide, which is a metabolic waste product, and this is what you breathe out.
What is the atmosphere made of on Venus?
It is mostly carbon dioxide, 97 %, at a pressure 90 times that of earth's atmosphere at sea level.
Is the atmosphere on Venus mostly Methane?
No. The atmosphere of Venus is mostly carbon dioxide with some nitrogen and trace amounts of other gasses.
what percent of the air do humans breath is oxygen?
Approximately 20%. The nitrogen we bresth in remains inert, and is just exhaled, with the carbon dioxide.
What is the atmotshere of mars made of?
Mostly (about 98%) by Carbon Dioxide, Nitrogen, Argon.
Do you breathe in more oxygen or nitrogen?
you breathe in more nitrogen then oxygen because there is 78% n in the air and 21% o in the air
