Using Navier-Stokes function and the continuity principle of mass, a set of mathematical model is established for the developing flow in the artery under unsteady condition in this paper. And then the solution is obtained by applying the method of Bessel function for this mathematical model. A set of formulas of velocity distribution and pressure distribution is derived. The comparisons between both pressure distributions of developing arterial blood flow in the steady and in the unsteady condition are determined. The analysis indicates that the distinction of pressure distribution for the steady and that for the unsteady condition is quire large.
