Changes That Occur in the Urinary System with Aging Include

Question

Changes that occur in the urinary system with aging include all of the following except
A) a decline in the number of functional nephrons.
B) a reduction in the GFR (glomerular filtration rate).
C) increased sensitivity to ADH.
D) problems with the micturition reflex.
E) loss of sphincter muscle tone.

Accepted Answer

Aging typically leads to a decrease in the number of functional nephrons and a reduction in the GFR. Problems with the micturition reflex and loss of sphincter muscle tone are common in older adults, but increased sensitivity to ADH is not a change that occurs in the urinary system with aging.
