The function of the kidney relies on maintaining a constant glomerular filtration rate (GFR). The kidney maintains the GFR at approximately 120 ml/min over a wide range of conditions, including arterial pressures of between ~75 and ~200 mmHg. The GFR is maintained by vasomotor adjustments of the afferent and efferent glomerular arterioles.

In this tutorial, you will explore some of the mechanisms by which GFR is maintained. Click the Next button below to begin.
