Inhaled air contains more oxygen than exhaled air because the cells have not yet used that oxyginated air.
Inhaled air is richer in oxygen than exhaled 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.
It is probably more accurate to say that you breath in air, a mixture of gases which contains about 21% oxygen and 0,04% CO2, and you breath out a mixture of gasses which contains a far greater concentration of carbon dioxide than you inhaled (about 5% of the mass of all the exhaled gas).
There is more Carbon Dioxide (CO2) when we breathe outbecause some of the Oxygen (O2) is absorbed into the blood via the lungs, and CO2 is removed from the blood, into the lungs. (O2 converts to CO2 in the body)However, this is only a small change so we still breathe out Oxygen: (which is why CPR works)Breathing In: 21% O2, 0.04% CO2Breathing Out: 17% O2, 4% CO2 (about 4% change in both)
ONE oxygen molecule (O2) contains two atoms of oxygen (O).
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
Inhaled air is richer in oxygen than exhaled air.
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
Yes
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.
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!
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
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.
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.
Yes, the air leaving the lungs has accumulated some of the moisture on the alveolar surfaces (inside of the lungs), this leaves with the exhaled air, making it more humid (more water vapour) than inhaled air.Aside from this and the higher temperature of exhaled air, it is pretty similar to that being inhaled. The concentrations of carbon dioxide and oxygen have altered also, more carbon dioxide leaves than enters, and more oxygen enters than leaves. This is due to removing carbon dioxide from the blood and taking in oxygen to remove metabolic waste and fuel metabolic processes respectively.Note that not all the oxygen inhaled is absorbed into the blood, and that the exhaled air contains other gases found naturally in the air such as minute proportions of the noble gases and nitrogen.
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.
