Video Summary:
Blood flow is a quantity of blood that passes a given point in the circulation in unit time. Laminar blood flow is seen when blood flows at a steady rate through a long and smooth blood vessel. Here velocity increases as we go from the vessel wall to the center. Turbulent flow occurs in case of very high blood flow, obstruction in a vessel, sharp turn and rough surface. Reynolds number is the measure of the tendency for turbulence to occur. Large diameter of larger vessels and high velocity in high cardiac output conditions tend to cause turbulence whereas the viscosity of the blood tends to prevent it. Murmurs produced by turbulence are important in measuring blood pressure and in the diagnosis of some conditions like vessel stenosis, shunts and cardiac valvular lesions.
