Study Notes
Renal Physiology: Key Concepts
- Body fluid compartment volume depends on solute amount
- Disturbance in ECF osmolarity causes water shift across cell membranes
- Renal Plasma Clearance (C) is the ratio of urinary excretion to plasma concentration
- Inulin Clearance equals GFR, as inulin is freely filtered and not reabsorbed or secreted
- Creatinine Clearance estimates GFR, but 10-20% is secreted by the proximal tubule
- Plasma creatinine levels approximate GFR, used to assess renal damage severity
- Demographics affect serum creatinine levels, influencing GFR estimation
- Tubular Transport estimation uses filtered and excreted loads
- Renal Blood Flow (RBF) is high, about 20-25% of cardiac output at rest
- RBF and GFR are regulated by afferent and efferent arteriolar resistances
- RBF Autoregulation occurs between 80 and 180 mmHg MAP, maintaining constant GFR
- Renal Plasma Flow (RPF) measurement uses Para-aminohippurate clearance to indicate effective RPF
