Line 1: Line 1:
 +The movement of [[blood]] through the vessels. It is pulsatile in the large [[arteries]],​ diminishing in amplitude as it approaches the [[[capillaries]]. In the veins it is nonpulsatile. The flow in arteries is the result of ventricular ejection; in the [[vein]]s it is a result of a number of factors including respiratory movement, muscle compression and the small residuum of arterial pressure.
 +**Effective renal blood flow (ERBF)** ​
 +That portion of the total blood flow through the [[kidney]]s that perfuses functional renal [[tissue]] such as the glomeruli.
 +**Laminar blood flow**
 +Blood flowing through a large [[blood vessel]] moves forward in a series of concentric laminae that slide over each other like a telescoping radio aerial. The central lamina moves fastest; the outer layer may be stationary.
 +**Renal blood flow, effective**
 +The amount of blood flowing to the parts of the kidney that are involved with the production of constituents of urine. It is that portion of the total renal blood flow that perfuses functional renal tissue (e.g., the glomeruli). It should be differentiated from renal [[plasma flow]], effective which is based on the amount of plasma rather than on total renal blood. ​
 +**Turbulent blood flow**
 +Created when blood flows through a small caliber orifice. Is the cause of murmurs in the heart and large arteries.
