5. Arterial end of Capillary
Outward Forces
Capillary Hydrostatic pressure Pc=30 mm of Hg
Negative Interestetial fluid
pressure Pif =3 mm of Hg
Interestitial fluid colloid
osmotic pressure =8 mm of Hg
Total Outward Force =41 mm of Hg
Inward Forces
Plasma Colloiud Osmotic pressure=28 mm of Hg
Net Filtration Pressure (41 – 28) = 13 mm of Hg

6. Venous end of Capillary
Outward Forces
Capillary Hydrostatic pressure Pc=10 mm of Hg
Negative Interestetial fluid
pressure Pif =3 mm of Hg
Interestitial fluid colloid
osmotic pressure =8 mm of Hg
Total Outward Force =21 mm of Hg
Inward Forces
Plasma Colloiud Osmotic pressure=28 mm of Hg
Net Reabsorption Pressure (28 – 21) = 7 mm of Hg

7. Starling Equilibrium for capillary Exchange
Outward Forces
Mean Capillary Pressure =17.3 mm of Hg
Negative Interestetial fluid
pressure Pif =3 mm of Hg
Interestitial fluid colloid
osmotic pressure =8 mm of Hg
Total Outward Force =28.3 mm of Hg
Inward Forces
Plasma Colloiud Osmotic pressure=28 mm of Hg
Net Outward Force (28 .3– 28) = 0.3 mm of Hg
