Liquids flow down pressure gradients (delta P) from regions of higher pressure to
regions of lower pressure
- For this reason, blood can flow in the cardiovascular system only if one region
develops higher pressure than other regions
- The heart creates high pressure when it contracts
Blood flow is the volume moved and is measured in mL/min (volume moved per unit
time)
- Delta P (pressure difference between two points) = P1 - P2
- The higher the pressure gradient, the greater the fluid flow
