Normal hemodynamic properties of the human aortic bifurcation. The dimensions are based on data given in [3]. The flow rate is taken from [66] and the pressures from [51]. The parameters of the two RCR models were calculated as described in the text. The resulting wave speed at mean pressure is cm = 6.26 m s−1 in the abdominal aorta and cm = 7.4 m s−1 in both iliac arteries.
