Compare and contrast inhaled and exhaled air?
Inhaled air contains mainly oxygen to be extracted. Exhaled air is mainly carbon dioxide as the waste product of breathing.

it is because the air which we take in is dirter and it gets purified in our nose
The air you exhale normally contains 19% less oxygen than inhaled air, with a 4% to 5% level of carbon dioxide and other gases, along with added water vapor. (Which is why you… can rebreathe it to control "hiccups".) Your body will continue to remove the remaining oxygen and add more carbon dioxide until the exhaled air is almost all nitrogen and CO2. So if you had only this air to breathe, your body would not be able to keep functioning and you could pass out and eventually die. This is the same situation as when one or more persons are trapped in a closed space with a limited amount of air. The considerable oxygen content (17%) in exhaled air allows mouth-to-mouth resuscitation in CPR.
Respiration or breathing. respiration is the more scientific term. The scientific formula for respiration is O2+C6H12O6(glucose)=CO2+H2O
Oxygen is absorbed from inhaled air and used by the body, so there is less oxygen to be exhaled.
because the air we take in is dirty and gets purified in our nose
It will burn longer in inhaled air, as it contains more oxygen than exhaled air.
Basically when you inhale air, the blood capillaries warm the incoming air so when you breathe out, you breathe the warm air warmed by the blood capillaries.
The air we inhale comes from the athmosphere; the percentage of CO2 in the athmosphere is next to insignificant. The air we exhale comes from the cellular environment; cells g…ive off CO2 as part of their metabolism, thus CO2 venous blood concentration is high
The air you inhale will have more oxygen in it than the air you exhale. The air you exhale will have more carbon dioxide in it than the air you inhale. Oxygen is taken up …in the lungs, and carbon dioxide is released. Note that there will be other things in the air that are absorbed, and other things that the body will release into the air to be exhaled. And not all the oxygen in the air you inhale will be taken up. That's why "rescue breathing" or "mouth to mouth" is effective. The primary gas exchange that takes place is the O2-CO2 exchange. Just to touch on the "extras" here, any carbon monoxide you inhale will be taken up faster and more effectively than oxygen (that's why it's dangerous.) Also, if you have been drinking alcoholic beverages, the alcohol will be present in the air you exhale. These are just two examples of the complex exchanges that take place in the lungs, as pointed to by the examination of air taken in and air expelled.
The percentage inhaled is roughly 79% but it is only 74% when exhaled. The volume of Nitrogen does not change but the percentage out of all the exhaled gas decreases as there …is far more CO2 and Water Vapour. Nitrogen itself not actually used up by the body, it is simply a byproduct of the nitrates and various emissions involved in photosynthesis from plants and various algae that get pumped with whimsical abandon into the atmosphere. Typical trees. Lest not forget the delicate equilibrium between humans and plants.
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 bloo…d 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 we breathe in is far from pure oxygen, but roughly by volume 78 per cent nitrogen, 21 per cent oxygen, 0.965 per cent argon and 0.04 per cent carbon dioxide (plus some he…lium, water and other gases). The permanent gases in air we exhale are roughly 78 per cent nitrogen, 15 to 18 per cent oxygen (we retain only a small amount), 4 to 5 per cent carbon dioxide and 0.96 per cent argon, the CO2 being of course used by plants during photosynthesis. We only use use up a little oxygen on what we actually breathe, and what we exhale, CO2 increases. And the other gases we breathe just goes in and out of our system.
If you don't know, then look somewhere else because answers.com knows NOTHING. But if you really need to know the answer, it's water and carbon dioxide.
The inhale increase the chest cavity will increase.
Because we need oxygen, and that is why we breathe at all. When we inhale, our body absorbs some of that oxygen, so when we exhale, there is less to be found.
Exhaled air has a much higher percentage of CO2 compared to inhaled air; there is also a lower percentage of oxygen in exhaled air compared to inhaled air - but the difference… is not so great as the body can only absorb a small amount of the oxygen which is in each lungful of air, so much of it gets breathed out again. CO2 content of the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times as much). Humidity of the inhaled air is dependent on the geographical place.
Exhaled air contains CO2 (Carbon Dioxide) and Inhaled air contains O2(Oxygen).
