[II C 4; Table 5.3]. Dilation of the afferent arteriole will increase both renal plasma flow (RPF) (because renal vascular resistance is decreased) and glomerular filtration rate (GFR) (because glomerular capillary hydrostatic pressure is increased). Dilation of the efferent arteriole will increase RPF but decrease GFR. Constriction of the efferent arteriole will decrease RPF (due to increased renal vascular resistance) and increase GFR. Both hyperproteinemia ( $\uparrow \pi$ in the glomerular capillaries) and a ureteral stone ( $\uparrow$ hydrostatic pressure in Bowman space) will oppose filtration and decrease GFR.
