WebDec 27, 2024 · Filtration is the movement of fluid out of the capillary and reabsorption is the movement of fluid back into the capillary. In most capillary systems of the body, there is a small net filtration (typically about 1% of plasma) of fluid from the intravascular to the extravascular compartment. Capillary fluid filtration exceeds reabsorption. WebKf,crelates net transcapillary fluid movement (filtration or absorption) to the net pressure gradient established by the transcapillary hydrostatic and oncotic pressure gradients.

WebAug 13, 2024 · The total daily diffusional turnover of water across all the capillaries in the body is huge (eg 80,000 liters per day) and is much larger than the total capillary blood flow (cardiac output) of about 8,000 liters per day. Diffusion occurs in both directions and does not result in net water movement across the capillary wall. WebFluid movement across a capillary wall is determined by a combination of hydrostatic and osmotic pressure.

WebIn other words, the oncotic pressure tends to pull fluid into the capillaries. In conditions where plasma proteins are reduced, e.g. from being lost in the urine ( proteinuria ), there will be a reduction in oncotic pressure and an increase in filtration across the capillary, resulting in excess fluid buildup in the tissues ( edema ). WebThus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration. Osmotic pressure drives the reabsorption of fluid from tissue back to the capillaries The net pressure that drives reabsorption—the movement of fluid from the interstitial fluid back into the capillaries—is called osmotic pressure.
