The lungs don't separate oxygen from nitrogen. The air enters the bloodstream as the oxygen/nitrogen mix breathed in. The oxygen gets used by the cells and replaced with carbon dioxide. The carbon dioxide/nitrogen mix is returned to the lungs and expelled.
Nitrogen in the bloodstream is the primary cause of what is known as "the bends" in divers. The rapid decrease in pressure caused by rising too fast from deep water causes nitrogen molecules to expand and accumulate in a diver's joints, causing extreme pain. Compression, an increase in pressure, is the only way to alleviate the bends, either by returning to a deeper depth or by spending time in a compression chamber.
Nitrogen is essential in the human body, it is needed to make up amino acids, which in turn make up proteins. It is also needed to make nucleic acids, which form DNA and RNA It is used to make carbohydrates. Without protein and DNA we would not be alive, both of which need nitrogen. It is essential for us.

How do animals get their nitrogen they need?
well, herbivores eat plants (which have nitrogen in them due to help from nitrogen fixating bacteria) then other animals eat herbivores. Since animals are heterotrophs they have to get their nutrients from other organisms.
If nitrogen is so abundant in our atmosphere compared to oxygen why aren't there nitrogen breathing lifeforms?
Because really, Nitrogen in its gas from is a very inert substance. Even Legume plants that "fix" nitrogen in the air expend a lot of energy doing so. So in a way it's more worth while using oxygen, which is more reactive than nitrogen.
What is tidal volume breathing?
Tidal volume breathing refers to the amount of air that enters and leaves the lungs during a single breath while at rest. It is typically around 500 mL for an average adult. Tidal volume is important for delivering oxygen to the body's tissues and removing carbon dioxide.
What happens when person talk and swallow at the same time?
Talking and swallowing at the same time can result in choking or aspiration, where food or liquid enters the airway instead of the esophagus. This can lead to coughing, difficulty breathing, and in severe cases, aspiration pneumonia. It is important to avoid talking while swallowing to prevent these complications.
How is nitrogen -15 isotope different from a nitrogen -9 isotope?
Nitrogen-15 has 15 protons and neutrons, while nitrogen-9 has only 9 protons and neutrons. Nitrogen-15 is a stable isotope, while nitrogen-9 is not stable and undergoes radioactive decay.
What happens to the wavelength of light when it enters a glass slab from air?
The wavelength of light decreases as it enters a glass slab from air. This is because the speed of light is slower in glass than in air, causing the frequency of the light to remain constant while its wavelength decreases.
What causes morning dry mouth?
One of the most common reasons is because you are breathing through your mouth while you sleep. This most often happens when you have a cold.
When is blood oxygenated?
while breathing
What happens if you mix nitrogen with argon?
When nitrogen is mixed with argon, the properties of the mixture will depend on the ratio of the two gases. Argon is a noble gas that is inert and does not react easily with other substances, while nitrogen is also relatively inert. The resulting mixture would most likely retain characteristics of both gases without any significant chemical reactions occurring.
What is the diffrence between fixed nitrogen and free nitrogen?
Fixed nitrogen refers to nitrogen compounds that have been converted from atmospheric nitrogen by bacteria or through industrial processes, while free nitrogen refers to nitrogen gas (N2) that exists in the atmosphere in its elemental form. Fixed nitrogen is more readily available for use by plants and animals, while free nitrogen is inert and must be transformed into a usable form before it can be utilized.
What happens to a sound wave when it enters a denser medium?
When a sound wave enters a denser medium, its speed decreases and its wavelength also decreases while the frequency remains the same. This causes the sound wave to bend towards the normal line at the boundary between the two media.
Should you rise in the court when its called out what happens if you don't?
It is customary to rise when the judge enters or departs the courtroom and when the jury enters and departs the court room. If you don't you may get a lecture from the judge and a cool place to sit for a while while you ponder the advisability of standing when directed. As a defendant, why would you even want to annoy the judge or jury who is going to decide your fate?
