[APARTHEID]

The lungs don't store air in the body, they're how the body diffuses O2 into blood and CO2 out of it.

Take both lungs out and you'd be utterly incapable of taking oxygen into your blood. Having two tanks to replace both your lungs would result in near instantaneous death from OXY damage.

One lung and one tank should mean that you have an internal store of oxygen that's depleted if you reach a LOSEBREATH situation. The tank would able to be slowly refilled via using external-internals, and it's pressure and contents could be measured using an atmospherics scanner. A consequence might be much lower stamina, due to having only one lung.

You can also do something previously fatal by using a canister in an extremely unorthodox manner.
