Glomerular filtration rate - Wikipedia

WebGlomerular filtration rate (GFR) is a measure of how well the kidneys filter blood and is considered the best overall index of kidney function.

WebIn the physiology of the kidney, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 25% of cardiac output, amounting to 1.2 - 1.3 L/min in a 70-kg adult male.It passes about 94% to the cortex.
