Venous return and the physical connection between distribution of segmental pressures and volumes.

Conclusion: the (Pms - Pra)/F formulation was never about Pms physically driving venous return; it was about how intravascular volume distributes among compliant compartments in accordance with their flow-dependent distending pressures, arbitrarily expressed relative to Pra rather than arterial pressure.
