What is normal renal blood flow?

The normal renal blood flow (RBF) in humans is approximately 1,100 to 1,200 milliliters per minute (mL/min). This represents about 20-25% of the total cardiac output.

RBF is a crucial physiological parameter as it ensures the proper functioning of the kidneys in filtering waste products, regulating fluid and electrolyte balance, and producing essential hormones like erythropoietin and renin.
