In this paper we outline the development of a 1D finite volume model to solve for blood flow through the arterial system. The model is based on a staggered spatial discretiza- tion which leads to a stable solution scheme. This scheme can accurately capture the various pressure wave reflections at locations with distinct discontinuities (in both area and material properties) as well as naturally treat branching vessels. We investigate the behaviour and per- formance of the solver for both a stented and branching vessel and finally for a full arterial network consisting of 55 arteries within the human vascular network.
