This is the third volume of the comprehensive series on Struc ture and Function of the Circulation, edited by Dr. Colin J. Schwartz with the collaboration of Nicholas T. Werthessen and Stewart Wolf. Dr. Schwartz, an authority on vascular structure and function and a respected investigator in this field for many years, selected as authors for the chapters an outstanding group of scientists from various parts of the world. As indicated in the Preface, the impetus for this broad treat ise evolved from the scientific sessions of three interdisciplinary international conferences held in Lindau in 1970, in Heidelberg in 1973, and Totts Gap, Pennsylvania, in 1976 as well as from numerous informal discussions. The subjects dealt with in these three volumes range from the roots of our knowledge in ancient history to the most recent inform ation on contractile proteins of smooth muscle cells. The structure, distribution, and dynamics of arteries, veins, and lymphatics are described in chapters on the systemic circulation as well as that of the heart, the vessels themselves, the brain, nerves, and viscera. Descriptions of ultrastructure, histochemistry, metabolism, and func tion of endothelium and of vascular smooth muscle and of vascular changes in aging are all included in the vast scope of this under taking.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Dr. Colin J. Schwartz, the scientific editor of this volume, has stated in his preface that this series is based on the needs identified by two scientific conferences, one in Lindau in April of 1970, and the other held in Heidelberg in October of 1973. Since those conferences, numerous data about vascular disease have been accumulated. Even though atherosclerosis remains the major cause of death in industrial countries, evidence in affluent societies points toward a decline in arteriosclerotic death- strokes and myocardial infarction in particular - during recent years. The most prominent example comes from the U. S. , but other high-risk regions such as eastern Finland, have also reported a decline. Most likely, this development stems from a change in so called environmental risk factors. Volume II of this handbook deals further with the structure and function of the circulation and con sequently addresses the basic physiological and anatomical elements which are ultimately responsible for the pathological and anatomical changes in the arterial system. While not specifically devoted to the description of disease, this volume nevertheless touches on rele vant pathogenetic and etiologic mechanisms. More than a century ago the pathogenesis of atherosclerosis in its initial phases had been described by VIRCHOW. He made endothe lium the centerpiece of his observations. The morphology of the endothelium and its function playa key role in the manifestations of atherosclerosis. Our knowledge about the function of these cells have yielded important insights.

The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.
