Blood flow and wave propagation in the systems of
compliant tubes filled with a fluid have been examined
as a model of the systemic circulation and the
intraorgan arterial networks have been modeled as
Windkessel elements or regular treelike
branching structures. Real intraorgan
vasculatures possess some geometrical regularity
and can be modeled as fractal-like trees. Nevertheless
blood flow in the real beds and their self-similar
models have some differences. Moreover real vasculatures
often have anastomoses which provide
additional pathways for blood flow and wave
propagation and reflection. Arterial beds in the small
and large intestine, in stomach and limbs have arterial
anastomoses that influence input admittance spectra of
the beds in comparison with the tree-like systems.
