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.
What else can I help you with?
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
Which two gases are which you exhale more than inhale?
Carbon dioxide is exhaled more than it is inhaled, as it is a waste product of metabolism. Nitrogen is also exhaled more than it is inhaled because it makes up a large percentage of the air we breathe, but is not used by our bodies.
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.
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 exhaled air has more water vapour?
No. The exhaled air contents more water vapour. The exhaled air is almost saturated with water vapour.
Does inhale air has more oxygen or exhaled air?
Inhaled air has more oxygen compared to exhaled air. When we inhale, we take in fresh oxygen from the environment to use for cellular respiration. As we exhale, we release carbon dioxide and the remaining oxygen that was not used by the body.
Which contains more oxygen inhaled air or exhaled air?
Inhaled air contains more oxygen than exhaled air. When you breathe in, oxygen is taken into your lungs and absorbed into your bloodstream. When you breathe out, you release carbon dioxide produced by your body and some of the oxygen has been used up.
How does the oxygen and carbon dioxide content of exhaled air differ from inhaled air?
Exhaled air has higher levels of carbon dioxide and lower levels of oxygen compared to inhaled air. This is because the body takes in oxygen from the air and releases carbon dioxide as a waste product during the process of respiration.
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!
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 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.
What does exhaled air contain more of than inhaled air?
More Oxygen, because some of it is processed into Carbon Dioxide (CO2).
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.
Which two gases are which you exhale more than inhale?
Carbon dioxide is exhaled more than it is inhaled, as it is a waste product of metabolism. Nitrogen is also exhaled more than it is inhaled because it makes up a large percentage of the air we breathe, but is not used by our bodies.
