In high elevation, mountainous areas, the air is very thin, meaning the oxygen molecules are more spread out. When people began living in these mountains, breathing was obviously an issue, since there was less oxygen to breathe. These people's bodies have adapted over the years, and they generally require less oxygen. Their body produces more red blood cells to carry oxygen as well.
The lungs (even one lung) are much bigger than the heart.
Not necessarily, but in general, yes.
No because they still have to breathe like others do to.
Not really stronger, but males have bigger chests proportionally, which can hold bigger lungs.
No. Athletes typically have better and bigger lungs. So do people who play woodwind and brass musical instruments. Bagpipers often have the best lungs, of all.
they have bigger hearts and lungs to get more oxygen from the thin air.
The lungs expand.
When you inhale, you breath in oxygen and your lungs get bigger.
Bigger lungs, more air.
the diaphragm is a bit bigger.
Some spiders, bigger ones such as tarantulas, do have book lungs.
Because they have very tiny lungs. The bigger the lungs-the slower the breath.
