Primary age-related differences in passive biomechanical metrics. Mean ± SEM values (solid points and vertical bars) interconnected by smooth lines and SEM area (shadow area) of (a) loaded diameter, (b) in vivo axial stretch, (c) axial stiffness (d) elastically stored energy, (e) circumferential stretch, and (f) circumferential stiffness, defined at age-specific ex-vivo equivalent diastolic (blue symbols) and systolic (black symbols) pressure for the DTA samples used for microstructural parameterization. Overbars denote statistical significance between ages (the color identifies the pressure), where * p<0.05, ** p<0.01 and *** p<0.001. A more detailed description of the passive mechanical function can be found in Figure S8.
