Shown are inflated volume $V_{\mathrm{infl}}$; contracted volume $V_{\mathrm{cont}}$; time of maximal contraction $t_{\mathrm{cont}}$; inflation fraction (IF), ejection fraction (EF). Spearman-$\rho$ values for correlation: inverse of wall thickness ($\mathsf{Wt}$), inverse of curvature ($\mathsf{C}$), inverse of (thickness $\times$ curvature) ($\mathsf{WtC}$) each versus stress at inflation (${\rho }_{\mathrm{infl}}^{\bullet }$) and contraction (${\rho }_{\mathrm{cont}}^{\bullet }$)
