Fluid movement in capillaries
WebJul 30, 2024 · There is no net movement of fluid near the midpoint of the capillary since CHP = BCOP. Net reabsorption occurs near the venous end of the capillary since BCOPis greater than CHP. Practice Question … 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.

WebNov 10, 2024 · As blood begins to move into capillaries from the arteries, the small size of the blood vessel increases blood pressure. Since blood pressure is higher than osmotic pressure, fluids containing... 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 2, 2024 · Starling's principle: Transvascular fluid exchange depends on a balance between hydrostatic and oncotic pressure gradients in the capillary lumen and the interstitial fluid. This balance can be expressed as the Starling equation: Jv = Lp S [ (Pc - Pi) - σ(Πc - Πi) ]; where Pc - Pi is the capillary-interstitial hydrostatic pressure gradient 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.
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 ). WebPhysical Factors that Determine Capillary Fluid Exchange. There is a free exchange of water, electrolytes, and small molecules between the intravascular and extravascular compartments of the body. The primary site of this exchange is capillaries and small post-capillary venules (collectively called "exchange vessels").
WebIn the aorta, the blood travels at 30 cm/sec. As blood moves into the arteries, arterioles, and ultimately to the capillary beds, the rate of movement slows dramatically to about 0.026 cm/sec, one-thousand times slower than the rate of movement in the aorta. ...
