When the afferent arteriole is constricted it causes blood to be unable to flow into the glomerulus, overall decreasing hydrostatic pressure and causing the bowman's capsule to decrease filtration.

The efferent arteriole is a small artery bringing blood into the glomerulus. Since it is an artery, it is under higher pressure than a vein of the same size. Vasoconstriction would lower pressure in the glomerulus as the blood supply is being reduced at this point. The rate of filtration would be reduced and urine production would also be reduced.
