Knowledge of hemodynamic principles is crucial to an understanding of cardiovascular physiology. This topic can be effectively taught by discussing simple physical principles and basic algebraic equations. A variety of examples from everyday observations can be used to illustrate the physical principles underlying the flow of blood through the circulation, thereby giving the student an experiential feel for the topic in addition to an understanding of theory. Moreover, opportunities abound for showing how each hemodynamic principle can explain one or another functional feature of the cardiovascular system or a cardiovascular pathophysiological state. Thus hemodynamics can be used as an organizational thread to tie together other aspects of cardiovascular physiology.
血流动力学原理的知识对于理解心血管生理学至关重要。通过讨论简单的物理原理和基本代数方程,可以有效地教授这一主题。可以使用各种日常观察中的例子来说明血液在循环中流动所依据的物理原理,从而使学生在理解理论的同时,对该主题有亲身体验。此外,有很多机会展示每个血流动力学原理如何解释心血管系统的一个或另一个功能特征或心血管病理生理状态。因此,血流动力学可以作为一条组织线索,将心血管生理学的其他方面联系在一起。
