A
Vital capacity is the most amount of air that can be made to pass into and out of the lungs by the most powerful inhale and exhale
4
Q
What are the long term benefits of respiratory system when doing regular exercise?
A
Improved lung efficiency Efficient carbon dioxide removal Increased vital capacity More alveoli available More blood vessels
5
