Answer the following question.
Effective filtration pressure was calculated to be 20 mmHg; where glomerular hydrostatic pressure was 70 mm of Hg. Which other pressure is affecting the filtration process? How much is it?

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
