We present a theoretical study of the dynamics of a thick polar epithelium subjected to the action of both an electric and a flow field in a planar geometry. We develop a generalized continuum hydrodynamic description and describe the tissue as a two component fluid system. The cells and the interstitial fluid are the two components and we keep all terms allowed by symmetry. https://www.kaliboat.com/product-category/pump-accessorieshydraulic-pumps-plumbingpumps-industrialhydraulics-pneumatics-pumps/
