Description	Various constitutive models were proposed for the description of behaviour of soft biological tissues, e.g. vascular wall tissues. In some cases, however, a better agreement between simulations and experiments can be achieved by using micropolar (Cosserat) theory of elasticity, which incorporates local rotations of points as well as their translations used in the classical elasticity theory, and couple stresses (torque per unit area) as well as the force stresses (force per unit area). The applicability and better credibility of this theory was proven experimentally: a much better agreement was achieved by using Cosserat theory instead of the classical theory in simulations of torque of wet bones. However, the micropolar theories under finite strain conditions and identification of their material parameters are still not described sufficiently in literature. In the paper the possibilities of using theories of micromorphic materials are analysed, for hyperelastic composites as well as for soft tissues.
