Vascular resistance is a fluid layer in which at a distance δ, viscosity η is a function of δ written as η(δ), and these surrounding layers do not meet at the vessel centre in real blood flow. Instead, there is the plugged flow which is hyperviscous because holding high concentration of RBCs. Thurston assembled this layer to the flow resistance to describe blood flow by means of a viscosity η(δ) and thickness δ from the wall layer. The blood resistance law appears as R adapted to blood flow profile : where Blood resistance varies depending on blood viscosity and its plugged flow
Resistance artery Resistance artery A resistance artery is small diameter blood vessel in the microcirculation that contributes significantly to the creation of the resistance to flow and regulation of blood flow. Resistance arteries are usually arterioles or end-points of arteries. Having thick muscular walls and narrow lumen they contribute the most to the resistance to blood flow. Degree of the contraction of muscles in the wall of a resistance artery is directly connected to the size of the lumen. Functionally from physiological point of view blood vessels can be divided in several categories Particular feature of resistance vessels is ability to change
