If the GFR drops, how does that affect the speed of filtrate through the nephron?

A. Filtrate moves faster

B. Filtrate moves slower

C. Filtrate speed doesn't change

Option B, Filtrate moves slower

Explanation:

GFR stands for Glomerular filtration rate. GFR increases with the increase in blood volume and its pressure. GFR indicates how much filtrate is formed by the renal corpuscles per minute. As the GFR increases, the urine production also increases and as the GFR decreases, the urine production also decreases due to the reduction in the speed of filtration.

Hence, option B is correct
