Shear stress is a measure of the force per unit area that acts parallel to a surface, resulting from the frictional forces between fluid layers moving at different velocities. In the context of blood flow, shear stress plays a critical role in determining how blood vessels respond to changes in blood flow and pressure. It influences endothelial cell function, vascular remodeling, and can impact conditions such as atherosclerosis and hypertension.
congrats on reading the definition of shear stress. now let's actually learn it.
