Document Summary

Maximum amount of air human lungs can hold is 5l on every breath. Amount of air we exhale/inhale depends on: health, age, level of activity. Lung volumes and lung capacities: 4 basic lung volumes and capacities, lung capacity consists of 2 or more lung volumes. Tidal volume: volume of air entering or leaving the lungs during one breath at rest (500ml) Inspiratory reserve volume: maximum amount of air that can enter the lungs in addition to the tidal volume (2500ml) Expiratory reserve volume: maximum amount of air that can be exhaled beyond the tidal volume (1000 ml) Residual volume: remaining air in the lungs after maximal expiration (1200ml) Inspiratory capacity: maximum amount that can be inhaled after exhaling the tidal volume (=tidal + inspiratory reserve) Functional residual capacity: amount still in lungs after exhalation of tidal volume (=expiratory reserve + residual volume) Vital capacity: maximum amount that can be exhaled after maximal inhalation (inspiratory reserve+tidal+expiratory reserve)
