The amount of inhaled air compared to the quantity of air exhaled by an average human is shown in the graph below.
This illistration was copied from Dr. Jay Wile's "Exploring Creation With Physical Science" book. Page 35/ Figure 2.5.
One would think that one should inhale the oxygen and exhale CO2 and those are the only substances involved, but that is not the case. One would also wonder why God did not make it so that the quantity of oxygen contained in the air 100% (or at least 85%), but that also is not the case, why? Well, first of all, notice that we inhale a lot of oxygen, as well as exhale a lot of oxygen, because normally we do not need al of oxygen we inhale, so we exhale the excess oxygen. Second of all, if the air contained too much oxygen, it would be way too violent on the lung tissue.

What is the concentration of oxygen in inhaled air?
Exhaled air contains 16% oxygen and 21% when inhaled.
Compare inhale air and exhale air?
Exhaled air - is the carbon dioxide that we breath out as a product of cellular respiration. Inhaled air is the oxygen we take in that is required for the process of cellular respiration. Along with the oxygen we take in are other elements such as Nitrogen, which we don't use and it doesn't harm us. It's just a by product of breathing.
What percentage of your blood works to carry oxygen throughout your body?
You have about 20% oxygen in inhaled air and negligible carbon bi oxide. You have about 4% carbon bi oxide in the exhaled air. That means 4% of the oxygen is absorbed from the blood. That makes it 4%/20%= 20% of the oxygen from the inhaled air is absorbed in your blood.
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
Why does inhaled air contain more oxygen than exhaled air?
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.
Does inhale air has more oxygen or exhaled air?
Inhaled air is richer in oxygen than exhaled air.
How much oxygen does exhaled air contains approximately?
A small percent . exhaled air always contains oxygen .
What gas shows the greatest difference in percentage between inhaled and exhaled air?
Oxygen is the gas that demonstrates the largest difference in percent between air that is inhaled, and air that is exhaled. The symbol for oxygen is O.
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.
What percentage of each gas is in the air?
When you inhale air the concentration is abut 21% of oxygen but in your lungs some of it gets consumed and replaced by carbon dioxide the concentration of exhaled oxygen depends on your metabolism and oxygen consumption.
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 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.
What are the differences between the surrounding air and exhaled air?
The air you breathe out is little changed from the air you breathe in, except that the oxygen content is somewhat lower - your body extracts some (not all) of the oxygen. The exhaled air is the same except for slightly lowered oxygen content.
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
What is the concentration of oxygen in inhaled air?
Exhaled air contains 16% oxygen and 21% when inhaled.
When air is exhaled it is rich in what?
oxygen
