| Abstract | Semileptonic B decays allow to determine the magnitudes of the CKM matrix parameters |V_cb| and |V_ub|, two fundamental parameters of the SM flavor sector. In addition, the observed rate of semitauonic B decays has been consistently above expectations since these decays were first measured. At Belle II these measurements use both exclusive decays such as B -> D*lnu and B -> pilnu, and inclusive X_clnu or X_ulnu final states restricted in phase space. The low-background collision environment at Belle II, along with the possibility of partially or fully reconstructing one of the two B mesons in the event, offer high precision. Recent results on |V_cb| and |V_ub| are presented along with recent Belle II results on lepton flavor universality tests. |
