Study Notes
Glomerular Filtration Rate (GFR)
- GFR is determined by the pressure across the glomerular wall
Forces Affecting GFR
- Three main forces affect GFR:
- Glomerular capillary hydrostatic pressure
- Bowman's capsule hydrostatic pressure
- Oncotic pressure (osmotic pressure due to protein concentration in blood)
