n the paper,the steady flow of blood through a small rigid circular tube with small tapering angles is discussed and blood rheology is assumed to be described by a micropolar fluid' Analytical expressions for flow velocities (both axial and radial),microrotational velocity, volume flow rate and shear stress at wall are obtained under the boundary conditions proposed by Condiff and Dahler. The numerical computations are performed and the effects of tapered angles and micropolar paramters on those quantities ...
