In contrast, constriction of the efferent arteriole decreases blood flow out of the glomerulus, and this increases the glomerular hydrostatic pressure and leads to an increase in GFR. Both the afferent and efferent arterioles are regulated through hormones (and drugs that inhibit the hormones).he 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.
Glomerular filtration is caused by the force of the difference between hydrostatic and osmotic pressure (though the glomerular filtration rate includes other variables as well). Key Terms glomerulus: A small, intertwined group of capillaries within nephrons of the kidney that filter the blood to make urine.
