उत्तर
The other pressure affecting the filtration process is osmotic pressure of blood and filtrate hydrostatic pressure.
Commonly effective filtration pressure (EFP) is represented as;
EFP = Glomerular Hydrostatic pressure in glomerulus – (Osmotic pressure of blood + Filtrate Hydrostatic pressure)
If EFP = 20 mmHg and Glomerular Hydrostatic pressure = 70 mmHg
20 = 70 – (Osmotic pressure of blood + Filtrate hydrostatic pressure)
∴ (Osmotic pressure of blood + Filtrate hydrostatic pressure) = 70 – 20
Then (Osmotic pressure of blood + Filtrate Hydrostatic pressure) = 50 mmHg
