How does the hydrostatic pressure change from the arterial end of a capillary to the venous end of a capillary? Do you see similar changes in colloid osmotic pressure?
Blood pressure at the arterial end of capillaries is about 40 mm Hg in humans. If blood pressure at the venous end is about 15 mm Hg, and colloid osmotic pressure is 25 mm Hg throughout, what is the net effect on fluid movement between capillaries and tissue spaces?
Hydrostatic pressure inside the capillary = 34 mmHgColloid osmotic pressure of the blood plasma = 27 mmHgHydrostatic pressure in the interstitial fluid = 2 mmHgColloid osmotic pressure in the interstitial fluid = 4 mmHgWhat is the total pressure favoring filtration?What is the total pressure favoring absorption?What is the net effect of these forces on fluid movement across the wall of the capillary?
