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.
1 Pressure Natriuresis: If renal perfusion pressure is increased then sodium excretion increases i.e. sodium excretion increases when blood pressure increases. 2  If more sodium is excreted less water is reabsorbed therefore the ECF volume decreases and blood pressure decreases.
