Is the Process of Glomerular Filtration?

Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.

Is glomerular filtration a passive process?

Filtrate is produced by the glomerulus when the hydrostatic pressure produced by the heart pushes water and solutes through the filtration membrane. Glomerular filtration is a passive process as cellular energy is not used at the filtration membrane to produce filtrate.

What is glomerular filtration based on?

Glomerular filtration is largely a function of glomerular filtration pressure, which in turn depends on renal perfusion pressure and, importantly, the balance between afferent arteriolar and efferent arteriolar tone.
