Due to the instructive role of the peristaltic phenomenon in the human body,interests have been developed in recent years towards peristaltic transport with various thermo-physical features.The current investigation reveals the effects of the magnetic field and variable transport properties on the peristaltic transport of a Casson fluid slip flow through an inclined channel.Nonlinear coupled partial differential equations regulate the fluid flow.Through the perturbation method,the momentum and energy equations are solved for small values of variable viscosity and thermal conductivity,and the closed-form solution is obtained for mass transfer.The impact on physiological quantities of related parameters of interest is evaluated and discussed via graphs.The results obtained for the current flow represent some interesting behaviors which have applications in the biomedical field.
