Human swallowing taking place in the pharynx is a complex process demanding precise co-ordination amongst the organs involved. People suffering from swallowing disorders are restricted to texture altered foods/drinks which are shear thinning necessitating the knowledge of shear deformation during pharyngeal transport. In this work, the shear rate during bolus transport using shear thinning boluses was measured and reported both during in-vivo and in-vitro experiments.
