Answer
The relationship is represented by the equation S/F=$\Delta$P/R/S
Where F= Blood Flow; $\Delta$P =change in pressure between two points ; R=Resistance of blood vessel
walls to blood flow.
Work Step by Step
This equation is patterned after Ohm's Law: I=$\Delta$V/R/S
Where I is current flow (amperes); V is volts and R is Resistance ( in ohms).
In the case of blood flow(F) , delta P is the driving or perfusion pressure; it is the pressure difference between any two points along a length of a blood vessel. R is the frictional resistance that a blood vessel wall offers to blood flow. Vessels are more resistant to turbulent or pulsatile flows than to steady or laminar flows. At the same driving blood pressure$\Delta$ P, blood flow is lower at a higher resistance and higher at a lower resistance. For organs, the perfusion pressure is the difference between the arterial pressure and the venous pressure of the organ's blood supply.
