Fig. 11

The important role of the cardiac model as an inlet condition for the distributed arterial model is highlighted comparing the output of the uncoupled aortic model (top left and right) and the fully coupled model (bottom left to right) settings, with a focus on the effects of ageing on the elastic arteries. On the left we depict the blood flow at the first element of the aortic model, in the center we show the aortic pressure (\(P_{\text {ar}}\)) at the same space element and at the bottom right we depict the pressure-volume loops in the left ventricle, for normal physiological conditions (black line) and for an arterial ageing conditions (blue line)
