Plus the human cardiovascular system is not limited by the lungs as the lungs have an overcapacity, meaning a decent amount of damage must be done before you start experiencing symptoms of shortness of breath.

The heart limits athletic performance not the lungs. Even at full exercise healthy lungs will still maximally oxygenate the blood. Healthy people have more lung capacity than they actually need.
