Summary:The model simulates a remote nervous control mechanism that integrates also the baroreflex role in systematic circulation hemodynamics influenced by postural effects. Parameters of the circulation consummatory organs have been modeled by addition or subtraction of metrics and baroreflex "increments" in accordance with the accepted controller structure. The basal vascular tone determined by the myogenic mechanisms forms a positive feedback with the initial tone value. Effects of the positive feedback are in balance with the negative feedback from smooth muscles of vessels. The baroreflex model does not require blood pressure setting from the outside for stabilization of blood pressure and other hemodynamic parameters. It supplements substantially the existing model of local vascular tone controllers interfered with postural effects.
