Which of the following responses to a fall in arterial pressure accounts for the ability of the kidneys to autoregulate glomerular filtration rate (GFR)?
A)Decreased resistance of the efferent arteriole
B)Increased delivery of fluid to the end of the proximal tubule
C)Increase resistance of the afferent arteriole
D)Increased [NaCl] in tubular fluid at the macula densa
E)Decreased resistance of the afferent arteriole

Decreased resistance of the afferent arteriole helps maintain GFR by allowing more blood to flow into the glomeruli, compensating for the fall in arterial pressure. This is a key mechanism in the autoregulation of GFR by the kidneys.
