title: Integration and regulation of cardiovascular function.
abstract: New methods in molecular biology and genetics have made possible many of the dramatic advances in physiological research that have occurred in recent years. For those of us who spend most of our time in the research laboratory, it si sometimes difficult to avoid a research-oriented, reductionist mind-set when discussing physiology with students. This article illustrates, with a few examples, the importance of conveying a "big picture" conceptual framework before discussing the details of cardiovascular physiology. Also, I have chosen examples from cardiac output and blood pressure regulation that show the importance of discussing cardiovascular physiology in terms of feedback control systems and integrating information from other areas, such as renal and endocrine physiology. Finally, I have highlighted the importance of two principles that I believe are often underemphasized in teaching physiology: mass balance and time dependence of physiological control systems.
