Splet2.1 Physical principles. Forces produced by blood flow on vessels can be divided into two vectors: one is perpendicular to the wall to create blood pressure, and the other is parallel to the vessel to induce shear stress (Fig. 2).Shear stress is a kind of frictional force acting on the apical surface of endothelial cells by blood flow.
