None! However, about 78% of what we breathe in and out is nitrogen.
75%
On average, exhaled breath contains about 4% carbon dioxide. This amounts to roughly 40,000 parts per million (ppm) of carbon dioxide.
Oxygen---------- 4-5 % Carbon dioxide---------- 20% Nitrogen--------- 75%
all of it
On average, humans breathe out about 3.5% of nitrogen in exhaled air, which is roughly 78% of the air we breathe in. This nitrogen is not utilized by the body and is simply exhaled back into the atmosphere.
without nitrogen our bodys would over oxygenate (get to much oxygen). nitrogen is important for plants, after all they breath in nitrogen and breath out oxygen.

Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
Too much of it can cause you to suffocate, however we take in a good amount of it every time we take a breath. inhaled air contains about 0.5 percent of co2 but exhaled air contains 4%-5% of co2
No, nitrogen makes up the majority of Earth's atmosphere at about 78%, while oxygen is the second most abundant gas at around 21%. Carbon dioxide is present in much smaller amounts, at about 0.04% of the atmosphere.
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
When you breathe out, the exhaled air contains approximately 16% oxygen, which is lower than the oxygen content in the air you inhale. The rest of the exhaled air is primarily made up of carbon dioxide and nitrogen.
