**5. Conclusions**

The current study explores the effect of MHD, heat transfer, and pressure distribution of thin layer flow of Casson nanofluid over a stretching upright cylinder. Two forms of CNTs, namely SWCNTs and MWCNTs, were picked as nanoparticles to be applied in human blood base fluid. The obtained set of coupled ODEs was solved by the HAM scheme. The influence of several embedded flow variables on velocity, thermal, and pressure distribution was derived and the derived result was investigated through graphs. The salient features of the current investigation are as follows:


**Author Contributions:** A.S.A. and T.G. modelled the problem and drew the physical sketch. S.N., S.I. and Z.S. introduced the similarity transformation and transformed the modeled problem into dimensionless form. K.S.N. and I.K. solved the problem numerically and computed the results. T.G. and I.K. discussed the results with conclusions. All the authors equally contributed in writing and revising the manuscript.
