The populations living at high elevations have to adapt to lower oxygen levels because at the sea level they at high altitude, there is less oxygen in the air that we breathe. This results that all of the blood from all areas of the lungs, is proportionally short on hypoxic.
What is hypoxia?
Hypoxia is refer to as the condition of the body in which the tissues are starved of oxygen. In its extreme form, where oxygen is entirely absent, the condition is known as anoxia.
The pressure on the body is about the same as ten meters of sea water pressing down on person body all the time. At sea level, air is compressible, then the weight of all that air at height compresses the air around us, making it denser. As the we go up a mountain, the air becomes less compressed and becomes thinner.
