Which of the Following is True of Glomerular Function

Question

Which of the following is true of glomerular function?
A) It is unaffected by blood pressure.
B) It is concerned with the filtration of 1.5 L/24 hr (of water).
C) A decline in GFR (glomerular filtration rate) causes polyuria.
D) An increase in GFR increases urine formation.

Accepted Answer

An increase in the glomerular filtration rate (GFR) leads to more fluid being filtered from the blood into the kidney tubules, which can increase urine formation. This is because more filtrate is produced for processing in the nephrons, potentially leading to an increase in the volume of urine produced if not reabsorbed.
