- Renal filtrate
- plasma minus blood cells and blood proteins
- most reabsorbed (99%)
- Filtration membrane: fenestrated endothelium, basement membrane and pores formed by podocytes
- Filtration pressure : responsibl for filtrate formation
- Glomerular capillary pressure (GCP) minus capsule pressure (CP) minua colloid osmotic pressure (COP)
- Changes caused by glomerular capillary pressure
- Glomerular filtrate, glomerular filtration rate (GFR)
- GFR=180 lt/day
- Inulin is used to calculate GFR
- Inulin can not be reabsorbed or secreted from tubules after filtration
- Urine and plasma amount of inulin are measured after it is given intraenously.
