Glomerular filtration rate is the amount of filtrate produced by both the kidneys within a minute.
Glomerular filtration rate is also defined as the amount of blood passing from the glomerulus to the Bowman’s capsule within a specified time period.
GFR for a healthy individual is 125ml/minute (i.e., 180 liters/day) and hence used as a measure of kidney function.
Glomerular filtration is the first step in the urine formation, during which blood is filtered by the glomerulus (tuft of capillaries).
Final Answer
Glomerular filtration rate is the amount of filtrate produced by both the kidneys within a minute. GFR in a normal individual is 125ml/minute.
