Webwww.nottingham.ac.uk Web02. avg 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. normal heart rate for 9 week fetus https://crystlsd.com
