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.
The rate of filtration from the glomerulus to the Bowman's capsule is determined (like in systemic capillaries) by the Starling equation 1  : GFR is the glomerular filtration rate. 2  K f is the filtration coefficient â a proportionality constant. 3  P gc is the glomerular capillary hydrostatic pressure.lood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole. The capillaries are lined by a layer of cells (an endothelium) that has a unique structure, allowing blood components to be filtered, and resulting ultimately in the formation of urine.
