Organisms obtain energy from their food through oxidative metabolism. Sugars are broken down to water and carbon dioxide and that requires oxygen. Humans extract oxygen from the air via their lungs so that the exhaled air has less oxygen (and also more carbon dioxide) than ambient air.

∙ 12y agoThe previous one sucks.
Mine is definitely better but not perfect.
The surrounding air has 21% of oxygen while exhaled air has 17%of oxygen.
The rest i am still researching pls add on to complete so people can use it as revisions and take note of it:)

∙ 12y agobecause when we inhale air all the dirt from the air is being transpor
Wiki User
∙ 11y agobecause the air we take in is dirty and gets purified in our nose
Wiki User
∙ 14y agoYes because the body removes some of the oxygen from the air and relaces it with Carbon dioxide before it is exhaled.
Wiki User
∙ 13y agoit is because the air which we take in is dirter and it gets purified in our nose

∙ 10y agoOxygen enters your body and carbon bi oxide leaves your body. That is the reason why you breath. So both the airs are bound to be different.

How does concentration of inhaled and exhaled air differ?
Inhaled air contains more oxygen than carbon dioxide and other gases. Exhaled air contains mostly carbon dioxide as the inhaled oxygen was used up to create energy. Waste carbon dioxide (and other unwanted gases) is then let out of the body and the cycle continues. :)Gas exchangeGas% in inhaled air% in exhaled airOxygen2116Carbon dioxide0.044Nitrogen7979
Will a candle burn longer in inhaled air or exhaled air?
Air contains about 21% oxygen, so the candle in air might only burn 21% as long as a candle in oxygen. Of course, that does not include other variables, like the candle burning in oxygen will burn hotter, melting the candle wax sooner.
Why exhaled air has more water vapour?
No. The exhaled air contents more water vapour. The exhaled air is almost saturated with water vapour.
What gas is more abundant in exhaled air than inhaled air?
Nitrogen is the most abundant gas in the atmosphere ( ~ 80% ) and therefore is the dominant species in both inspired as well as expired air.
Why is the oxygen percentage different in inhaled and exhaled air?
Oxygen must be dissolved into water, the colder the water, the better (this is the opposite for dissolving solids, where the hotter the water/solvent the more you tend to dissolve in it). Hence by boiling water we eliminate most of the dissolved oxygen (and other gases), giving you all those bubbles as it boils. In air however, it is free to merely float around and mix with whatever is there already (mostly nitrogen) - there is little or no pressure on it to condense to liquid or deposit as solid. Oxygen, at temperatures (and pressures) on the earth, tends to prefer to be a gas.
Does inhale air has more oxygen or exhaled air?
Inhaled air is richer in oxygen than exhaled air.
Which contains more oxygen inhaled air or exhaled air?
Inhaled air contains more oxygen than exhaled air because the cells have not yet used that oxyginated air.
How does the oxygen and carbon dioxide content of exhaled air differ from inhaled air?
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
Which gas does the exhaled air contain?
Exhaled air will contain all of the gases in regular air, except that it will have higher percentages of carbon dioxide and lower percentages of oxygen. (It still will have oxygen, or CPR wouldn't work.) It will also have water vapor from our lungs. The main gas in inhaled and exhaled air is nitrogen. This is followed by oxygen, then carbon dioxide, then other gases. Yes, there is still more oxygen exhaled than carbon dioxide, but at a smaller percentage than was inhaled. Chances are that your teacher is looking for the gas, carbon dioxide, as your answer, since that is the product of cellular respiration that is disposed of in exhaled air, but it isn't the main component of exhaled air.

What are the 3 main difference between the exhaled and inhaled air?
Exhaled air has less oxygen than inhaled air.Exhaled air has more carbon dioxide than inhaled air.Exhaled air is warmer that inhaled air.Maybe the first 2 are redundant, but I think that should work!
What is the differences between inhaled air and exhaled air?
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.
Is there a way of showing that exhaled air has more oxygen in it than inhaled air?
Exhaled air should have less oxygen since it is carrying the CO2 from your lungs in the first place. A way of showing... there may be
Does exhaled air contain more carbon dioxide or oxygen?
Carbon dioxide.
How is inhaled air different from exhaled air?
Because the body has used the oxygen in the air to oxidize the nutrients you eat, this process combines the oxygen that you inhaled with carbon which makes up part of the nutrients you eat to form a poisonous gas "carbon-dioxide" which is then transported back to the lungs and exhaled along with moisture.
What does exhaled air contain more of than inhaled air?
More Oxygen, because some of it is processed into Carbon Dioxide (CO2).
Which air contains more damp inhaled or exhaled air?
Yes
