At high altitude, there is less oxygen, so breathing rate is increased to compensate.
Because of the high altitude.
There is danger to a healthy person from high altitude breathing because the oxygen level is very low which could possibly cause a heart attack or stroke.
Your breathing can become laboured due to your smaller lung capacity in high altitudes.
Increase in breathing and heart rate
yes, the higher the altitude the thinner the air, thus the less oxygen in the air.
Pilot because it is thin at high altitude in non pressurized cabin.
B/c the higher you go the less air there is to breathe from.
The atmospheric saturation of oxygen decreases as altitude increases. Almost all humans can't live above 18,000 feet due to low oxygen concentrations
Alpacas have adapted to high altitude in several ways. One special way is that alpaca do not suffer from hypertension as humans and cattle when left at high altitude for long periods of time.
It is not so much as the composition that is important, it is that at higher altitudes there is less air. Air is about 20% oxygen, but the higher up you go in altitude, the thinner air will have less oxygen. That's what makes breathing more difficult at higher altitudes.
No, unless the number of red blood cells is very low.
