The quasi-one-dimensional Newtonian fluid flow in an active
vessel in which the inlet pressure oscillates about a mean value is considered. The vascular wall
is assumed to display the Bayliss effect and a reaction to changes in blood flow. The first is
characterized by the dependence of the contractility of the vascular smooth-muscle cells on the
intravascular pressure and the second by the sensitivity of the endothelial cells to the wall
shear stress. The dependence of the period-average radius and blood flow rate on the mean value
and pulsation amplitude and frequency of the inlet pressure is investigated numerically. The
characteristics are compared for the passive vessel, the vessel with the Bayliss effect, and the
vessel with both reactions.
