^no. we breathe in mostly nitrogen, and carbon dioxide. a small percentage of it is oxygen and argon. we take in the oxygen during respiration and use it for energy, thus expelling the unwanted debris as it were of CARBON DIOXIDE, and water vapour. the argon is so small it is not normally measured.
Inhaled air is richer in oxygen than exhaled air.
Approximately 20%. The nitrogen we bresth in remains inert, and is just exhaled, with the carbon dioxide.
Inhaled air contains more oxygen than exhaled air because the cells have not yet used that oxyginated air.
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.

The larynx (voicebox) is responsible for speech in humans, due to vibrations from exhaled air.
For humans, the waste substance is carbon dioxide.
Air that is exhaled passes from the trachea directly into the larynx.
The larynx (voicebox) is responsible for speech in humans, due to vibrations from exhaled air.
Inhaled air is richer in oxygen than exhaled air.
yes it is the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times) more
The composition of expired air in humans is usually: 17 % oxygen, 3. 5 % carbon dioxide, 79 % nitrogen, and temperature range of between 29 and 34 degrees Celsius, Moisture is usually a component of the expired air as well.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Approximately 20%. The nitrogen we bresth in remains inert, and is just exhaled, with the carbon dioxide.
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.
Carbon dioxide makes up most of the exhaled air in
CO2 makes up most of the exhaled air in vertebrates.
