Only rarely do we notice that we need them: our lungs. Mostly, we breathe unconsciously and shallowly – especially if we have a sitting job.
Only when we exert ourselves, for example when we run particularly far and fast, do we realise that our breathing quickens and becomes more laborious – or that we get out of breath sometimes.
This adaptive capacity of our lungs, their flexibility in responding quickly and effectively to various physical requirements is one of the many amazing abilities of our body which keep it viable.
Only when we inhale the oxygen supplied to our body via the lungs as the basis for combustion, are we able to generate the energy our body’s cells need to survive.
