Why is the afferent arteriole of a glomerulus wider than the efferent arteriole?
Original Khojo Papers practice question — not from a past board paper.
Answer
The difference in width makes the blood leave the glomerulus more slowly than it enters, so a high pressure is maintained inside the glomerular capillaries. That pressure is what drives ultrafiltration.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
A fall in this pressure reduces or stops the formation of urine.
