Effect of Blood Pressure Alterations

چکیده
Recent reports have provided evidence for the separation of red cells and plasma within the kidney (1-3). Pappenheimer and Kinter have proposed an ingenious theory of plasma skimming to explain this phenomenon (2). According to these authors the energy for the separation is derived from the arterial pressure. Hence, there should be less separation at low pressure, and more at higher pressure. To test the validity of this hypothesis, simultaneous red cell and plasma transit times through the kidney were measured at normal and at low arterial pressures in 12 mongrel dogs.

متن کاملMathematical modeling of blood flow in a stenosed artery under MHD effect through porous medium
In this investigation, a mathematical model for studying oscillatory flow of blood in a stenosed artery under the influence of transverse magnetic field through porous medium has been developed. The equations of motion of blood flow are solved analytically. The analytical expressions for axial velocity, volumetric flow rate, pressure gradient, resistance to blood flow and shear stress have been...
