Increases in systemic blood pressure will maintain renal perfusion pressure; however, constriction of the afferent and efferent glomerular arterioles will tend to restrict renal blood flow.
Os incrementos na presión sanguínea sistémica manteñen a presión da perfusión renal; porén, a constrición das ateriolas glomerulares aferentes e eferentes tende a restrinxir o fluxo sanguíneo renal.
