By: HWC, Views: 8202

• The glomerular filtration rate is the amount of filtrate formed per minute within the renal corpuscle. • Once the filtrate is formed it moves down the tubule. • The production and movement of filtrate depends on three pressures: I. Glomerular blood hydrostatic pressure (GBHP) is ...
