Balancing Loop Dynamics in Renal Autoregulation
Quick fact
Renal autoregulation is so powerful that it can maintain a constant glomerular filtration rate across a wide range of blood pressures (roughly 80 to 180 mmHg mean arterial pressure) without any input from the brain or hormones.
Why this is interesting
Your kidneys receive about 20% of your heart's output every minute. Even if your blood pressure suddenly spikes, your kidneys keep their filtration rate nearly constant—how do they manage that so quickly and precisely?
