To address your question, here's a basic picture of the glomerulus, from Gray's Anatomy. The afferent arteriole is in red, and the efferent arteriole in blue. The glomerular filtration rate (GFR) depends on the pressure difference between the two, which affects the hydrostatic pressure at the glomerulus. Constriction of the afferent arteriole decreases the blood flow into the glomerulus and thus the glomerular hydrostatic pressure, which leads to a decrease in GFR.
Constriction of BOTH Afferent & Efferent Arterioles, with preferential Constriction of the Efferent Arteriole. This results in a massive reduction in RBF/RPF and an increased in GFR. These are active under pathologic conditions (e.g. hemorrhage) NOT physiologic conditions.onstriction of BOTH Afferent & Efferent Arterioles, with preferential Constriction of the Efferent Arteriole.
