[Adaptation of resistance vessels to the transmural pressure level].
The transmural pressure level influences vascular structure and function. A short-term distension enhances sensitivity of the vascular smooth muscle to constrictor agonists. A long-term change in the blood pressure leads to structural autoregulation of arterial vessels. The resulting change of the wall thickness modifies performance of the distension-dependent mechanisms and alters thereby the pressure range in which the myogenic amplification of vasoconstriction is manifested.
