In order to have estimate of the quantitative effects of various parameters involved in the analysis computer codes were developed and to evaluate the analytical results obtained for resistance to blood flow, concentration profile and associated physiological diffusion variables for normal and diseased system associated with stenosis due to the local deposition of lipids have been determine. The results are shown in Fig 2-9 by using the values of parameter based on experimental data in capillary.

The Casson’s relation is commonly written as:
The Casson’s relation is commonly written as:
where 6 | |\denotes the maximum height of stenosis at z = (d +L o/m™/""~). The ratio of the stenosis height to the radius of the normal artery is much less than unity. R(z) and Ro are the radius of the artery with and without stenosis respectively. Lp is the stenosis length, d represents the location of stenosis and m is stenosis shape parameter. In the case of m > 2, stenosis shape parameter indicates an axially symmetric stenosis.

Fig 2-4 shows the results for resistance to flow for different values of stenosis shape parameter, stenosis length, stenosis size and yield stress. Resistance to flow decreases as stenosis shape parameter increases and increases as stenosis size, stenosis length and yield stress increases. Resistance to flow increase as stenosis grows or radius of artery decreases. This referred to as Fahraeus-Lindquist effect in very thin tubes. The present results are therefore consistent with the observation of Haldar [5, 4, 15]. Fig 5-
