Question

If the glomerular hydrostatic pressure is 70 mm, the glomerular plasma colloid osmotic pressure is 40 mm and the capsular hydrostatic pressure is 10 mm, then the net filtration pressure is

Answer 1

In this question we need to calculate the net filtration pressure. To do this we need to understand that we have two types of pressure:

1) Pressure that promotes filtration:

• Glomerular hydrostatic pressure

2) Pressure opposing the filtration:

• Capsular hydrostatic pressure
• Glomerular plasma colloid osmotic pressure

So Net filtration pressure

= Total pressure that promotes filtration

= ( Pressure prompting filtration) - (Pressure opposing filtration)

Hope this helps. Please let me know if you have any query.

Best wishes!!
