内容 This paper is intended to introduce to practical physicians some basic and current problems of the relation between blood pressure and blood flow in large arteries. The formation of the arterial pressure wave and flow wave and their deformation on a transmission through the arterial system are mainly explained by morphological character of arteries as elastic tubes. The theoretical models consisted of the elastic tubes with different properties (pulse wave velocity, reflection coefficient, attenuation constant) that were connected with each other in series are useful to explain the pressure and flow wave forms. Another important relation between pressure and flow is shown by the Bernoulli's equation. The equation relates the differences in pressure across a stenosis with the differences in velocity increases proportionally, and a modified version (ΔP=v^4) can be applied clinically for evaluation of stenotic severity.
