Define Glomerular Filtration Rate $(GFR)$.

(N/A) Glomerular filtration rate $(GFR)$ is defined as the total volume of glomerular filtrate formed by all the nephrons in both kidneys per minute.
In a healthy individual,the $GFR$ is approximately $125 \, mL/minute$,which amounts to about $180 \, liters$ per day.
The glomerular filtrate is essentially blood plasma minus the proteins,containing substances like glucose,amino acids,sodium,potassium,urea,uric acid,ketone bodies,and a large volume of water.
