Question
What forces promote glomerular filtration? What forces opposes them? What is meant by net filtration pressure?

Solution
Glomerular hydrostatic pressure (55 mm Hg) is the force that promotes filtration. The colloidal osmotic pressure (30 mm Hg) and the capsular hydrostatic pressure (15 mm Hg) are the two opposing forces.
The difference between the force promoting and opposing filtration is the net filtration pressure. It is responsible for filtration.
Net filtration pressure = Glomerular hydrostatic pressure – (Colloidal osmotic pressure + Capsular hydrostatic pressure).
