We analysed the morphology; formation history and the specific angular momentum content of simulated galaxies. We use for this study cosmological hydrodynamical simulations that include an effective; physically-motivated Supernova feedback; which is able to regulate the star formation in haloes of different masses. We found the discs to be formed by conserving the specific angular momentum in accordance with the classical disc formation model. Our results suggest that the survival of the discs is highly linked to their subsequent history of accretion and the relative alignment between the existing disc and the accreted material; in agreement with previous works.
