As 78% of the air consists of nitrogen, when we breathe the air most of what we breathe in is nitrogen, so, in a way, the answer is 'yes'.
However, this nitrogen has no effect on the workings of our body and so it is emitted again when we breathe out. The only gas in the air which is used by our bodies is oxygen which, when we breathe in, is absorbed by the lungs and passed to the bloodstream. At the same time waste carbon dioxide is passed from our bloodstream to the air we breathe out via our lungs. Around 21% of the air is oxygen which is only marginally reduced in the air we breathe out which explains why we can give mouth-to-mouth resuscitation as there is plenty of oxygen left even in air we breathe out - enough to keep someone else alive during resuscitation if necessary.
Yes, nitrogen is roughly 80% of the air you breath. However it simply acts as an inert gas, not being used by the body.
Humans breathe air order to obtain oxygen (20% of air).
The component of air that we're after is the second most abundant one ... oxygen,
comprising about 20% of what we breathe in. The #1 most abundant component of the
mixture, at 78%, is nitrogen. Since we are not plants, we do fine without nitrogen, and
simply breathe that part back out.
Some divers prefer to use a "breathing gas" that does not contain any nitrogen, in order to avoid "decompression sickness" (also called "the bends") and nitrogen narcosis.
Humans cannot breathe nitrogen, but it is necessary for living organisms. Microorganisms such as bacteria chemically change the nitrogen to nitrogen compounds that are then used by plants. Herbivores eat the plants, and carnivores eat the herbivores. In this way, animals are able to receive nitrogen in a usable form.
What else can I help you with?
Where do human get nitrogen in their diet?
Humans get nitrogen in their diet by eating plants (herbs etc) Hope this helps :)
Is nitrogen harmful to the human body?
If we were to inhale pure nitrogen, we would obviously die from lack of oxygen. Otherwise no, you have to understand that 70% of every breath you take is nitrogen
Is nitrogen important for survival?
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.
What is the primary component of an exhaled breath?
Nitrogen, there is 78% of nitrogen exhaled Nitrogen, there is 78% of nitrogen exhaled
Is nitrogen air?
Nitrogen makes up about ~80% of the air we breath in.
When do you use nitrogen?
Take a breath.
Bacteria changes nitrates in what way?
Bacteria breath in nitrogen and breath out nitrate/
Why human not die breathing mostly nitrogen in atmosphere?
Humans breathe a mixture of gases in air, not just nitrogen. Nitrogen itself is not harmful to humans in normal concentrations found in the atmosphere. However, breathing pure nitrogen can displace oxygen in the lungs and lead to asphyxiation.
What gas is unaffected when people breath?
Nitrogen.
What do we do with the nitrogen we breath?
When we breathe in air, about 78% of it is nitrogen. Our bodies do not use this nitrogen, so when we exhale, the nitrogen is released back into the atmosphere unchanged.
Is compressibility a gas?
Nitrogen is a gas that can be compressed. Not all nitrogen is compressed, for example the nitrogen in the air we breath is at atmospheric pressure.
What makes 78 percent of the air we breath?
Nitrogen.
