← Human Body & HealthWhich failure mode becomes likely when a person experiences chronic hypertension affecting the vessel walls of the afferent arterioles in the kidneys?
A)Increased glomerular filtration rate
B)Enhanced renin secretion
C)Improved sodium reabsorption
D)Glomerular capillary wall thickening✓
💡 Explanation
Chronic hypertension causes increased pressure on the afferent arterioles, which then triggers glomerular capillary wall thickening through a mechanism called hypertensive nephrosclerosis; therefore, the capillary walls thicken, rather than filtration increasing because damage reduces function.
