Blood vessels react to increased flow by vasodilatation, a response to increased shear stress that is detected by the endothelial cells, which signal the smooth muscle to relax. When changes in flow persist, there is restructuring of the vessel wall, including both cellular and noncellular elements, with significant change in luminal cross-sectional area and relatively small or no change in wall thickness. The end result of this vascular remodeling is normalization of wall shear stress as detected by the endothelium.
