Glomerular filtration rate is the amount of

Glomerular filtration rate (GFR) is indeed the amount of filtrate that is formed by the kidneys per minute. It provides a measure of the kidney's filtering capacity and is an important indicator of renal function. GFR reflects the efficiency of the glomeruli, which are the tiny filters within the nephrons of the kidneys, in filtering blood and forming the initial filtrate that will eventually become urine. GFR is influenced by factors such as blood pressure, blood flow to the kidneys, and the permeability of the glomerular filtration barrier. It's a key parameter for assessing kidney health and diagnosing kidney disorders.
