Kidney shrinkage with age is primarily due to the loss of glomeruli. As we age, the number of functional glomeruli decreases, leading to a decrease in renal function and a reduction in overall kidney size. The other options (spooling of collecting ducts, merging of proximal and distal convoluted tubules, and proliferating nephron loops) do not contribute significantly to kidney shrinkage with age.
