Which is Not One of the Changes in the Urinary

Question

Which is not one of the changes in the urinary system due to aging?
A) reduced blood flow to the kidneys
B) decrease in number of functional nephrons
C) decreased response to aldosterone and ADH
D) decreased glomerular filtration rate
E) gradual increase in kidney size due to fluid retention

Accepted Answer

Gradual increase in kidney size due to fluid retention is not a change that occurs in the urinary system due to aging. In fact, kidney size and weight tend to decrease with age. The other choices (reduced blood flow to the kidneys, decrease in number of functional nephrons, decreased response to aldosterone and ADH, and decreased glomerular filtration rate) are all changes that occur in the urinary system due to aging.
