Just think more! Where have you seen oxygen tanks? Firemen? Welders?

Lungs are most affected because they are mostly gas, and gasses are compressible. The rest of the body is mostly liquid and solid, and not very compressible. The problem for divers isn't the pressure, but the solubility of nitrogen and oxygen in the blood.

Where have you seen or heard an air compressor? Gas station? Paint shop? It's good to ask for help, but try thinking first. It's better for you.

1 - at high altitudes, air becomes too thin to be breathable

2 - stomach, skull, actually all the body parts are affected by the pressure

3 - to clean your keyboard! to blow up balloons easier than doing it yourself.
