Which of the following statements about glomerular filtration rate (GFR) is correct?

Options

Choose one · Correct answer highlighted

GFR is mainly controlled by blood pressure in the glomerulus. Correct GFR remains constant regardless of blood pressure fluctuations. GFR is independent of the juxtaglomerular apparatus. GFR is highest when the afferent arteriole constricts.

Explanation

GFR is primarily regulated by blood pressure in the glomerulus, which is influenced by the afferent and efferent arterioles.
