Study Notes
Autoregulation of Glomerular Filtration
- Kidneys can maintain relatively constant renal blood flow (RBF) and glomerular filtration rate (GFR) despite significant changes in arterial blood pressure.
- This is known as autoregulation.
- For example, if blood pressure fluctuates between 80 mmHg and 170 mmHg, the kidneys can still maintain stable RBF and GFR.
Intrinsic Control of Glomerular Filtration
- Kidneys can maintain renal blood flow (RBF) and glomerular filtration rate (GFR) relatively constant despite variations in arterial blood pressure.
- This ability to maintain stability is called autoregulation.
- Autoregulation allows RBF and GFR to remain consistent even when blood pressure fluctuates significantly, for example, between 80 mmHg and 170 mmHg.
Intrinsic Control of Glomerular Filtration
- Autoregulation enables the kidneys to maintain renal blood flow and glomerular filtration rate (GFR) relatively constant despite changes in arterial blood pressure.
- This means that even when blood pressure significantly fluctuates, the kidneys can still function effectively.
- Example: If systemic blood pressure varies between 80 mmHg and 170 mmHg, the kidneys can still maintain a steady renal blood flow and GFR.
