Calculate net filtration pressure with the following data: PGC = 42 mm Hg pGC = 12 mm Hg PBC= 16 mm Hg Assume that no proteins were filtered. 
Select and explain. 
A. 34 mm Hg, B. Data not sufficient, C. 14 mm Hg, D. 28 mm Hg
C: 14 mm Hg
Answer: C: 14 mm Hg 
Explanation: Force oring filtration = Glomerular capillary hydrostatic pressure(PGC = 42mm Hg) Forces opposing filtration = Plasma colloid oncotic pressure (pGC = 12 mm Hg) Bowman's capsule hydrostatic pressure (PSC = 16mm Hg) : Net = PsC + pGC = 12 + 16= 28mm Hg : NET FILTRATION PRESSURE = 42 - 28 mm Hg = 14mm Hg.
