Age-Related Changes in the Urinary System Include ________

Question

Age-related changes in the urinary system include ________.
A) an increase in the number of cortical nephrons
B) an increase in the overall amount of glomerular filtration
C) reduced sensitivity to ADH
D) greater reabsorption of water
E) increase in renal blood flow efficiency

Accepted Answer

With age, the sensitivity to ADH decreases, which can lead to decreased water reabsorption and increased urine output.

Answer: D
 With age, there is a decrease in the number and function of nephrons in the kidney, leading to a reduced ability to concentrate urine. This results in a greater need for reabsorption of water by the remaining nephrons to maintain fluid balance.
