Overview of the Circulation Interrelationships Among Pressure, Flow, and Resistance

Overview of the Circulation Poiseuille ’s law � The Poiseuille ’s works under restricted conditions: 1. Steady laminar flow

Overview of the Circulation Blood vessels and their resistance arranged in series and in parallel If the pressure difference between two points is 1 mm Hg and the flow is 1 ml/sec, the resistance is said to be 1 peripheral resistance unit, usually abbreviated PRU.

Overview of the Circulation Effect of Blood Hematocrit and Blood Viscosity on Vascular Resistance and Blood Flow

Overview of the Circulation The types of flow

Overview of the Circulation Effects of Pressure on Vascular Resistance and Tissue Blood Flow �The reasons: 1. Increases the force that pushes blood 2. Distends the vessels at the same time
