Abstract: | A model of the human arterial system was constructed based on the anatomical branching structure of the arterial tree. Arteries
were divided into segments represented by uniform thin-walled elastic tubes with realistic arterial dimensions and wall properties.
The configuration contains 128 segments accounting for all the central vessels and major peripheral arteries supplying the
extremities including vessels of the order of 2·0 mm diameter. Vascular impedance and pressure and flow waveforms were determined
at various locations in the system and good agreement was found with experimental measurements. Use of the model is illustrated
in investigating wave propagation in the arterial system and in simulation of arterial dynamics in such pathological conditions
as arteriosclerosis and presence of a stenosis in the femoral artery. |
