WebbCapillaries connect your arteries to your veins. Capillaries are the smallest type of blood vessel. They can be as tiny as 5 micrometers, which is less than a third of a hair's width. WebbShear stress is applied parallel to the vessel surface and is generated due to friction of the blood against the vessel wall. The effect of shear stress is borne directly by the endothelial lining of the blood vessel [].Shear stress (τ) is directly proportional to the blood viscosity (µ) and the rate of flow (Q): τ = 4µQ/πr 3, where r = vessel radius.
