Bile flow in the human biliary system plays a vital role in the pathogenesis of biliary diseases. In the present study, the effect of an overlapping stone in the cystic duct on the flow characteristics of bile is observed. The mathematical model here, considers a two-fluid model of bile, consisting of a core region of suspension of bile salts, cholesterol and bilirubin and peripheral layer of mucosa. The expression for the flow characteristics like the resistance, the wall shear stress, and the stress at the throat and at the critical height of stone is studied. It is observed that as the peripheral viscosity decreases the resistance to flow and the shear stress also decreases.
