Heat and mass transfer in blood flow through a tapered artery with mild stenosis is examined. The blood is considered to be an incompressible, micropolar fluid flowing through a vessel with nonsymmetric axial and symmetric radial axes. The geometry of the model takes into account the shape parameter, tapered angle and height of the stenosis.The variation in the shape parameter is used to describe the changes in the axial shape of the stenosis in the artery. The governing equations for the model, comprising the continuity, momentum, energy, and mass transfer equations are transformed and simplified under the assumption of mild stenosis. Analytical solutions for the equations are obtained. The effect of different parameters on temperature, concentration, velocity, resistance, shear stress, pressure drop, Nusselt number, and Sherwood number are presented in graphical form, analysed and discussed. It is discovered that the blood temperature increases as micropolar spin parameter or the particle size increases. Also, its concentration is slowed down with an increase in the micropolar parameter or coupling number. The temperature in the converging artery is higher than that of diverging artery when compared under the same conditions.
