WebbOncotic pressure is the presumed main absorption force in capillary-interstitial fluid transfer and represents one half of the equation of Starling’s law [11]. Thus, as it has proved wrong, the law must be wrong! This was the reason for repeated calls to reconsider Starling’s hypothesis [8].

WebbThis equation is a variation of Starling's law that shows that hydrostatic and osmotic forces work _______ one another to drive the filtration and reabsorption of materials across a capillary membrane. hydrostatic colloid osmotic NFP = (HPb − HPif ) − (COPb − COPif) against During liver disease, levels of blood proteins may be low. WebbDon’t need to know the equation just understand the concept. Hydrostatic pressure will draw fluid out of the vessels, while oncotic pressure draws fluid back in. Basically on the arterial side the hydrostatic pressure is higher than osmotic (oncotic) pressure due to the elastic recoil of the muscular arterioles, and that hydrostatic pressure forces fluid out …
