One of the respiratory purposes of the mouth is to warm and moisten the air for the lungs to draw the oxygen out of it. That's the reason why even when it is very cold outside, you can see your breath, because the warm moisture is "frozen" (basically).
Well, what happens,A lot of things happen. But, if you mean what happens because the air is cold, plants die, animals die, some say it's easier to breathe. (And it's usually cold when the barometric pressure is high.)
the lungs will moves down when breathe out air
Because your body warms the air as you breathe in - the air retains heat as you exhale.
That is where it breathe in water and if you blew air into its gill you would drown it in air
We draw air into, and expel out of, the lungs.
It just stays really cold because 0.0000000001 is higher then -1 and at -1 degrees air is just regularly cold
All that happens in the humans air sacks is that the air that u breathe gets stored up in there
bahaha umm? you cant breathe, then you die!
The air pressure is high when the air is cold, and it's sinking.
It does for me because it makes it harder to breathe. I have asthma.
The lungs act a bit like baloons. When you breathe in they will inflate, when you breathe out they will deflate. Using a balloon may be useful way to understand this, breathe into the balloon and it will inflate (this is what happens when you breathe in). Next, leave the air out (slowly) and this is what happens your lungs when you breathe out.
Fog appears when cold air sinks to the ground.
