Circulatory Physiology I. Factors Involved in Blood Circulation A. Blood Flow - the actual VOLUME of blood moving through a particular site (vessel or organ) over a certain TIME period (liter/hour, ml/min) B. Blood Pressure - the FORCE exerted on the wall of a blood vessel by the blood contained within (millimeters of Mercury; mm Hg) blood pressure = the systemic arterial pressure of large vessels of the body (mm Hg) C. Resistance to Flow (Peripheral Resistance) - the FORCE resisting the flow of blood through a vessel (usually from friction) 1. viscosity - a measure of the "thickness" or "stickiness" of a fluid flowing through a pipe a. V water < V blood < V toothpaste b. water flows easier than blood 2. tube length - the longer the vessel, the greater the drop in pressure due to friction 3. tube diameter - smaller diameter = greater friction D. Relation Between Blood Flow, Pressure, Resistance difference in blood pressure ( P) Blood Flow (F) = peripheral resistance (R) a.
