Answer 1

The osmotic pressure of blood that opposes ultrafiltration is about 30 mm Hg. 

Explanation:

GHP is the pressure through the glomerular which is about 55 mm of Hg. This pressure is opposed by OP = 30 mm of Hg and capsular BP = 15 mm of Hg. Hence net effective filtration pressure EFP = 10 mm of Hg.
