Vesicular breath sounds are normal breath sounds heard over the lung's periphery,caused by air moving through smaller airways;the inspiratory phase is three times longer than the expiratory phase.In bronchovesicular breath sounds,the inspiratory phase is equally as long as the expiratory phase.In bronchial breath sounds,the expiration phase is longer than the inspiration phase,at a 3:2 ratio.
