Abstract Artery aneurysm / stenosis segment is not very widespread but has gained growing recognition due to their frequent incidence in pediatric and young adult patients. The present analysis theoretically investigates the physical traits of electro-magneto-hydrodynamics (EMHD) of blood stream in the presence of electroosmotic forces via arteries having both aneurysm and stenosis for a hybrid fractional second-grade nanofluid. The governing equations for the proposed paradigm are solved and closed-form solutions are obtained for the cases of mild stenosis and aneurysm. Exact expressions for the hemodynamic velocity, heat transfer, resistance impedance and wall shear stress for the flow are obtained. Graphical representations for the effects of the relevant parameters on the physical variables of flow characteristic are plotted and discussed. Special cases of our flow model are derived. It has been deduced that the hemodynamic velocity decreases for spherical-shaped nanoparticles than those of rods, bricks, and platelet-shaped nanoparticles. The present model has the intention to be useful in medical pumps for drug delivery system.
