without it, it is impossible to get oxygen in and carbon dioxide out.
Assuming you need your lungs, yes.
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.
From the air drawn into the lungs by movement of the diaphragm
Mouth & nose to trachea to bronchi to lungs.
the blood absorb oxygen in the lungs(cappilaries)
You need your lungs to breathe. Without lungs, you'd be dead.
You need lungs to breathe.
Of course. They need lungs to breathe.
snakes and frogs need lungs to help them breath becuse when they grow they don't grow with gills they grom with lungs instead.

lungs are tubes that transfer blood from your heart to your lungs and other parts of your body. (doesn't need to be improved)
your lungs
Lungs.

No, you need lungs for that.
Yes, they do have lungs as they need to breath air.
you need it to survive
