Biofluid dynamics is also an example of a biological fluid. Types of Fluids Fluids can be classified into four basic types. They are: An Ideal Fluid is a fluid that has no viscosity, means it will offer no resistance, pragmatically this type of fluid does not exist. It is incompressible in nature. Real fluids are compressible in nature. They offer some resistance and thus have viscosity. All Fluids existing are real fluids. A Newtonian Fluid is a fluid whose viscous shear stresses (acting between different layers of fluid and between the fluid layer and surface over which it is flowing) are directly
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
