Is nitrogen necessary for breathing?
Nitrogen is an inert gas and is not necessary for breathing. Oxygen on the other hand is quite necessary. Without a sufficient partial pressure of oxygen in your breathing mix, you will become unconscious and if it is low enough, you can even die. For certain types of dives, nitrogen is reduced and sometimes completely removed from the breathing mix due to its narcotic effects at higher partial pressures. Dives have been done with helium and even hydrogen as substitutes for the nitrogen in the breathing mix due to their reduced narcotic effects at higher partial pressures. Not all insert gases work well though. Some are even more narcotic than nitrogen (e.g. argon, xenon).
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.
How do humans add nitrogen to the atmosphere?
Humans add nitrogen to the atmosphere primarily through the burning of fossil fuels, which releases nitrogen oxides. Agricultural activities, such as the application of nitrogen-based fertilizers, also contribute to nitrogen emissions into the atmosphere.
Is nitrogen gas toxic?
Nitrogen gas is not toxic to humans in normal atmospheric concentrations. However, breathing in pure nitrogen gas can lead to asphyxiation because it displaces oxygen in the air, leading to a lack of oxygen in the bloodstream.
Explain why levels of nitrogen are why levels of nitrogen are the same in air breathed in as air breathed out?
When we breathe in, we inhale air that contains nitrogen. This nitrogen enters our bloodstream but is not utilized by the body. When we breathe out, the nitrogen is simply released back into the air because our bodies do not extract or alter nitrogen during the breathing process. Therefore, the levels of nitrogen in air breathed in and breathed out remain the same.
How is nitrogen poisonous to humans?
Breathing 100% of it... No oxygen...
What process supplies animals and fungi with nitrogen?
Breathing.
Is breathing nitrogen painful?
No. You breathe nitrogen with every breath you take. It is 78% of Earth's atmosphere.
What are nitrogen and oxygen used for?
Well, breathing, for one XP
If you breathe in pure nitrogen what will happen?
Breathing in pure nitrogen can be extremely dangerous as nitrogen does not support human respiration. When you inhale pure nitrogen, it displaces oxygen in your lungs, leading to a lack of oxygen in the bloodstream, which can result in rapid suffocation and death. It is important to always ensure proper ventilation and air quality to prevent accidental inhalation of pure nitrogen.
Why do we need nitrogen i the atmosphere?
Without nitrogen in the atmosphere, we would be breathing in nearly pure oxygen, which would be fatal.
Is nitrogen necessary for breathing?

Can humans breathe nitrogen safely?
No, humans cannot breathe nitrogen safely as it does not provide the necessary oxygen for respiration. Breathing pure nitrogen can lead to asphyxiation and suffocation.
What does a mix of nitrogen and oxygen make?
nitrous oxide? <><><><> Air you are breathing right this second is a mix of nitrogen (79%) and oxygen (21%)
Can you breathe nitrogen safely?
No, breathing pure nitrogen can be dangerous and even deadly because it can displace oxygen in the air, leading to suffocation.
What is nitrogen necessary for?
Nitrogen is necessary for life on earth. Without nitrogen, which makes up some 78% of the earth's atmosphere, we would be breathing in nearly pure oxygen and that would be fatal.
What two gasses are used in spacecraft to provide breathing air for astronauts?
oxygen and nitrogen
