As the Urinary System Ages

Question

As the urinary system ages
A) the number of nephrons decreases
B) the blood flow to the kidney is reduced
C) the muscles of the bladder begin to atrophy
D) all of the above

Accepted Answer

As the urinary system ages, all of the given statements are true. The number of nephrons decreases, reducing the kidney's ability to filter waste and excess fluids from the blood. Blood flow to the kidneys is reduced, leading to decreased renal function. Atrophy of bladder muscles reduces bladder capacity and can result in incontinence.
