This new, comprehensive analysis of human cardiovascular control explains the control of pressure, vascular volume and blood flow during orthostatis and exercise. Analysis of the physical properties of the vascular system and their modification by mechanical, neural, and humoural factors is highlighted by novel graphical representations of basic concepts. Interactive effects of the vasculature on cardiac performance and factors that both control and limit oxygen transfer from lungs to cells are stressed. This complete account will prove invaluable for all medical students, physiologists and clinicians who wish to better understand the reflex and hormonal control of the human cardiovascular system.

About the Author
Loring B. Rowell is a Professor of Physiology and Biophysics and of Medicine (Cardiology) at the University of Washington School of Medicine.

It is a delight to read the historical perspective provided for each of the major concepts discussed as that allows the reader to gain an understanding of the early contributions by a number of scientists to the concepts of cardiovascular control accepted today. Pertinent headings are presented throughout to ease digestion of the wealth of information provided. The illustrations are excellent, each elaborating concepts presented in the text. The author has provided mini summaries at the end of each section so that major points of importance are emphasized ... when finished with this volume I had the feeling that I had just received a thorough education in current concepts of blood pressure regulation. * J.A.
