{Renal worksheet} In renal physiology, the filtration fraction is the ratio of the glomerular filtration rate (GFR) to the renal plasma flow (RPF). Filtration Fraction, FF = GFR/RPF The filtration fraction, therefore, represents the proportion of the fluid reaching the kidneys which passes into the renal tubules. It is normally about 20%. The GFR ... Found on http://en.wikipedia.org/wiki/Filtration_fraction
(from the article `renal system`) Estimation of the GFR and RPF allows the proportion of available plasma perfusing the kidney that is filtered by the glomerulus to be calculated. ... Found on http://www.britannica.com/eb/a-z/f/25
The fraction of the plasma entering the kidney that filters into the lumen of the renal tubules, determined by dividing the glomerular filtration rate by the renal plasma flow; normally, it is around 0.17. ... (05 Mar 2000) ... Found on http://www.encyclo.co.uk/local/20973
