A slight increase in blood pressure from normal should cause ________ stretch in the afferent arteriole. In response, the afferent arteriole should ________ to stabilize glomerular filtration rate. 1) decreased, vasodilation 2) decreased, vasoconstriction 3) increased, vasodilation 4) increased, vasoconstriction 5) any of the above

Step 1
The glomerular filtration rate (GFR) refers to the rate at which blood is filtered through the glomerulus. If the afferent arteriole were to dilate (vasodilation), it would increase the blood flow into the glomerulus. This would result in an increased GFR. On Show more…

Which of the following circumstances would increase glomerular filtration rate? Select one: a. Constriction of the afferent arteriole and dilation of the efferent arteriole b. An increase in the capsular hydrostatic pressure c. A decrease in the blood colloid osmotic pressure d. A decrease in the glomerular hydrostatic pressure

'An increase in glomerular filtration rate (GFR) will: Produce a myogenic response, which signals the afferent arteriole to vasodilate Stimulate the macula densa to secrete sodium Stimulate the macula densa, which signals the afferent arteriole to vasodilate Stimulate the macula densa, which signals the afferent arteriole to vasoconstrict None of the above'
