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.
However, when hormones like aldosterone and ADH are present, the higher blood pressure does NOT necessarily result in an increased urine output. This is because the hormones act on parts of the nephron that are distal to the glomerulus (aldosterone on the DCT, ADH on the collecting duct).
