When we inhale pure Oxygen (O2) at normal atmospheric pressure a highly reactive form of atomic Oxygen creates inside our lungs which destroys proteins and membranes in the epithelial cells. However the astronauts in Apollo program have reported that they did not suffer from any harmful effects having to breathe pure O2 at low pressure for two weeks.
Oxygen is essential for all of us. But if we breathe pure Oxygen for a while it could lead us to death. What may be the reason behind this?
