partitioning of pulmonary resistance of 15 excised human and 5 canine lungs by means of a retrograde catheter demonstrated that the share of peripheral airways ( with an id of 2.4 mm or less ) and of lung tissue in pulmonary resistance was markedly larger ( 44-96 % ) in humans than in dogs ( 41-59 % ) .
