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.

When the lungs inhale oxygen what does it exhale as a waste?

The lungs largely exhale carbon dioxide and water vapor along with  the non-oxygen components of the air taken in (such as nitrogen).

What happens to cause air to be exhaled from the lungs?

  the diaphragm relaxes and that causes the ribcage to compress (get smaller) this pushes air out, and you have exhailed

What happens when you inhale the air you exhale?

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

What happen to your lungs as you exhale air?

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

How much nitrogen is inhaled and exhaled air?

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

What is the differences between inhaled and exhaled air?

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

What are the components of inhaled and exhaled 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

What gases are added to inhaled air and then exhaled?

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.
