Fluid Exchange Flashcards
FLuid exchange across capillaries
More in regulaiton of PV than in exchange of nuterents
Allow passage of electrolytes and glucose but inhibit larger
Starling forces
Pc - favor filtration
Pif - favor absorption
COPp - favor absorption
COPif - favor filtration
Primary Starling forces
Pc - for filtraiton
COPp - for resorption
Vneous vs. arterial starling forces
Arterial - high Pc…means favors more of filtration

Capillary surface area effect
INc in metqabolic activity results in increase in number of open capillaries and increases SA available
