✦ Synopsis

\ simple model of prcssurc-flow relationship in blood vessels was developed. The calculation of the model component\ wri\ hased on velocity profiles in the vessels. The flat velocity profile in the entrance of the ~csscl was consldered. By using mean pressure over the cross-section and assuming a polynomial approximation of the velocity profile. it is shown that the re&ance of ;I vc55el \egmcnt increases with increased flatness of the velocity protile. Moreover. the an;llysis provtdes a mean> to calculate the resistance of a vessel segment based on the shape 01 the velocity proiilcs in th.ct kcgmcnt.
