Why is shear stress significant in vascular tissues?
Shear stress is the force per unit area exerted by fluid flow over a surface. In the context of histology, shear stress is critical in vascular tissues, particularly in the endothelium of blood vessels. Blood flow generates shear stress, which influences endothelial cell function, vascular tone, and angiogenesis. Abnormal shear stress can lead to vascular diseases such as atherosclerosis.
