Listed below are the hydrostatic and oncotic
pressures and filtration rate across a muscle capillary wall:
Capillary hydrostatic pressure (Pc) = 25 mm Hg
Plasma colloid osmotic pressure (Πp) = 25 mm Hg
Interstitial colloid osmotic pressure (ΠI) = 10 mm Hg
Interstitial hydrostatic pressure (PI) = −5 mm Hg
Capillary filtration rate = 150 ml/min
