The aim of this article is to measuring the blood flow, when they pass through obstructed blood vessels. In many medical arteries the amount of the blood flow inside canals and obstructed vessel is important and reduces due to the arteries. However, the problem with measurements in such circumstances lies in the lack of precise and appropriate experimental data needed for the calculation of the blood passes through the vessel. To overcome the shortcoming, hence, the effect of the most common type orifices, i.e., Square edge Orifice (D & D/2 taps), were put to the test, by simulating the flow with the use of CFD methods and Fluent 6.0 software, for 0.25 <=beta <= 0.5 and 10,000 <= Re-D <= 200,000, fixed temperature of 300(K). Therefore, relations were obtained for blood as the incompressible fluid. [Kharaji M. Gh., Dadjoo F., Alirezaei Y., Falavand A., Langari A.
