WebAlthough this pressure appears to be small when considered in terms of osmotic pressure (28 mm Hg ≈ 1.4 mOsm/kg H 2 O), it is an important force involved in fluid movement across capillaries (details of this topic are presented in the following section on fluid exchange between body fluid compartments). 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. WebCapillary exchange vessel adjustments during acute venous hypertension can modulate the efficiency of the alterations in transcapillary forces (NFP) and thereby capillary fluid filtration.
