Study Notes
Intrinsic Control of Glomerular Filtration
- Kidneys can maintain renal blood flow and glomerular filtration rate (GFR) despite large changes in arterial blood pressure
- This is known as autoregulation
- Autoregulation ensures that blood pressure fluctuations between 80-170 mmHg do not significantly affect renal blood flow and GFR
