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
