This card explains the pressure differences (hydrostatic vs. oncotic) in capillaries and their effect on tissue fluid formation and the reabsorption of fluid back into capillaries.
Tato karta vysvětluje tlakové rozdíly (hydrostatický vs. onkotický) v kapilárách a jejich vliv na tvorbu tkáňového moku a proces zpětného vstřebávání tekutin do kapilár.
Front | Hydrostatic pressure vs oncontic pressure, tissue fluid 3.1.2(d) |
---|---|
Back | - blood flows under high pressure from arterioles to caps (hydrostatic pressure), at arterial end of cap, HP forcing fluids out cap high (more than oncontic pressure of water entering cap) so fluid Squeezed out of cap - tissue fluid (fluid filling spaces between dells) ha same composition as plasma (without RBC and LPP) so diffusion occurs through tissue fluid - Blood moves through cap to venules, HP lower than oncontic pressure now (OC always same) so water moves into cap by osmosis and by time it reaches vein, 90% fluid back in vessel |
