Fig. 1From: Effects of tissue degradation by collagenase and elastase on the biaxial mechanics of porcine airwaysA The whole porcine lung with the left lung’s parenchyma removed reveals the main bronchial network. Three main airway regions are shown: the trachea large bronchi, and small bronchi. B Bronchial section with soft tissue attached to the cartilage, and C the isolated soft tissue specimen with denoted circumferential and axial orientation which was subjected to biaxial testingBack to article page
