Blood flow in the vascular system may be characterized as unsteady and passing through a network of tubes. The unsteadiness of the flow is due to the periodic output of the heart which serves as the pump. The model presented includes the effects of branching as well as non-linear elastic properties of the tube walls. Branches are included on a discrete basis where at each branch point a mass balance and two momentum balances are written, and these two equations, together with an additional equation, e. g. a lumped impedance for each branch, determine the flow conditions in the region of branching.
