- A A rise in glomerular filtration rate from higher blood flow
- B No change, since arteriole diameter does not affect filtration
- C A surge of glucose being secreted directly into urine
- D A fall in glomerular filtration rate from reduced blood flow
Correct answer: D. A fall in glomerular filtration rate from reduced blood flow
Explanation: Constriction of the afferent arteriole reduces blood flow and pressure within the glomerular capillaries, lowering the glomerular filtration rate.
Concept context
Nitrogenous waste, kidney structure, urine formation in the nephron, and hormonal regulation of excretion.
