two different pressures

physio flip

muscle or nervous tissue 

capillary wit hthe thin wall exchange nutrients

get stuff into the blood 

get stuff out of the blood 

swell up -edema 

fluid stay outside the blood  vessel 

normally reabsorb 

fluid been out of the blood 

hydrostatic pressure 

straw - fill up the straw with water ( water is being pull down by hydrostatic pressure ) 

basic the same thing happen in the capillaries

in the capillaries-CVS system fluid is force out through capillary wall 

just about all the time 

osmotic pressure 

water always flow towards 

higher concentration 

small hole - allow small perticle to pass 

much higher 

protein molecule 

concentration protein molecule 

water always flow 

water reabsorb to the vessel

blood serum protein compre outside the 

driven by osmotic or osmotic pressure ( tend to drive back in ) 

colloid -oncotic pressure 

protein 

ion sodium 

do not contribute the osmotic fluid 

filter 

reabsorb 

osmotic 

interstitial 

capillary 

equal to 

hydrostatic pressure 

small fraction 

final player 

lympatic system
