Why is it that when the afferent arteriole is constricted, the glomerular filtration rate is reduced?
#43 Answer Key: Sympathetic innervation of the kidneys primarily affects the afferent arterioles. This innervation constricts the afferent arterioles and reduces the glomerular filtration rate. The urine output will be dramatically reduced.
Why reduced and not increased?
