What would you like to do?
Do you inhale or exhale when the gases inside the lungs are pushed out through air passages?
Inhaled air contains mainly oxygen to be extracted. Exhaled air is mainly carbon dioxide as the waste product of breathing.
The lungs largely exhale carbon dioxide and water vapor along with the non-oxygen components of the air taken in (such as nitrogen).
Inhaled gases is oxegen and exhaled gases you CAN'T brethe in because it's carbon dioxide.
Inhaled air Nitrogen: 78% Oxygen: 21% Carbon Dioxide: 0.04% Water Vapour: 0.96% Exhaled Air Nitrogen: 78% Oxygen: 17% Carbon Dioxide: 4% Water Vapour: 3%
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.
When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the …chest cavity. This is done because the lungs become smaller
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.
Mainly oxygen and nitrogen.
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.
When this happens, your lungs and the rib cage (with muscles between each rib) expand when inhaling, and return to their previous size.
so you can get oxygen in you body Lungs inhale to supply the body with oxygen, they exhale to dispose of poisonous gasses such as carbon dioxide.

I believe that the pressure from the diaphragm causes our lungs inflate, thus we inhale and when the diaphragm deflates, it makes us exhale. -------------------------------…-------------------------------------- As your diaphragm or intercoastal muscles contract the size of the lungs increases. This creates a pressure difference between your lungs and the surrounding atmosphere. By increasing the size of the lungs you create a low pressure environment in the lungs by expanding the same amount of gas to a larger area. this pressure difference doesn't have to be much 1mmhg is more then enough, the main thing is just that you need a difference in preasure. Air flows from high preasure to low preasure, so by decreasing the preasure in the lungs air flows into the lungs. as you breath out you make the lungs smaller by relaxing the muscles and diaphragm, making the volume in the lungs decrease, thus increasing the preasure and moving the air from inside the lungs out to the surrounding atmosphere.
