The effect on the efferent arteriolar resistance is, however, markedly greater, in part due to its smaller basal diameter; this tends to increase glomerular capillary hydrostatic pressure and maintain glomerular filtration rate.
O efecto sobre a resistencia arteriolar eferente é, non obstante, marcadamente maior, en parte debido ao seu menor diámetro basal; isto tende a incrementar a presión hidrostática capilar glomerular e a manter a taxa de filtración glomerular.
