A fluid-active structure interaction problem applied to the case of blood flow in arteries is solved using the finite volume method for the fluid and the membrane theory for the solid. In this work the active properties of the arterial wall (autoregulation mechanisms) are taken into account and are represented in the model by a modification of the Theological parameters of the wall. The results show: (i) that we must consider the autoregulation law in the mathematical development of a model on arterial flow, and (ii) that the kinematics of the arterial wall seem to be more sensitive to the autoregulation mechanism based on shear stress than to the one based on pressure.
