Yes it does because it is a waste that your body does not need.
Carbon dioxide.
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
yes it is the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times) more
to check if exhaled air has more carbon dioxide
Helium is a relatively light gas which is lighter than air at ground level. Exhaled air contains a lot of water vapour and carbon dioxide relative to normal air. Since ground level air is less dense than helium, adding water vapour and carbon dioxide makes exhaled air even more heavier than helium.
Carbon dioxide is an end product of the matabolism in humans and other higher animals. Sugars, fats and amino acids are broken down to produce energy for the body and carbon dioxide is an unwanted by-product which is returned to the lungs and exhaled.
Carbon dioxide (CO2).
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.
More Oxygen, because some of it is processed into Carbon Dioxide (CO2).
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
Yes. When you breath, you take in oxygen and breathe out CO2. According to Wiki Answers (see link), an exhaled breath is about 4% CO2. Atmospheric CO2 is between 300 and 400 ppm, or 0.03% to 0.04%.
A living organism produces carbon dioxide from the sugars in food and the oxygen inhales with the air it breathes. This process creates the enery for body heat. processes and mvement. The carbon dioxide is taken to the lungs by the blood and exhaled.
