Biofluids such as blood, as well as other structured materials, exhibit rather complex rheological behaviour. In this paper, starting from a first‐order kinetic model, we developed a constitutive equation and studied its applicability to model biofluids. In particular, we studied the cases of simple shear flow, hysteresis and yield stress. Model predictions were successfully compared with experimental data on complex materials such as blood and a penicillin suspension.
