How are pressure and flow related
WebUnder ideal laminar flow conditions, in which vascular resistance is independent of flow and pressure, the relationship between pressure, flow and resistance can be depicted as shown in the figure to the right. Because flow and resistance are reciprocally related, an increase in resistance decreases flow at any ΔP. Alternatively, at a specific flow along a …
