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
