Kinematics of the artery demonstrating (A) stress-free configuration obtained by radially opening the artery into a sector, and cutting out a longitudinal strip, (B) load-free configuration with no internal pressure or longitudinal pre-stretch, and (C) the in vivo loaded state. Note that in the stress-free state, the longitudinal strip curves intimal outward[52], while the radially-cut ring curves intimal inward. The grid size in the inserts is 1mm. Green overlaid circles were used for morphometric analysis.
