Fig. 5From: Effects of tissue degradation by collagenase and elastase on the biaxial mechanics of porcine airwaysAverage ± standard deviation of the anisotropic ratio for the initial and final moduli for each lung region as determined by the circumferential divided by the axial direction. The initial modulus anisotropic ratio was less than one, exhibiting greater axial values, while the ultimate modulus anisotropic ratio was greater than one indicative of circumferentially leading anisotropyBack to article page
