Book Description
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.

Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Book Description
A generation past, the western realms were embroiled in endless war. Then the Destroyer came. From the blood and ashes he left behind, a tenuous alliance rose between the barbarian riders of Parsathe and the walled kingdoms of the south. That alliance is all that stands against the return of an ancient evil—until the barbarian king and queen are slain in an act of bloody betrayal. Though forbidden by the alliance council to kill the corrupt king responsible for his parents’ murders, Maddek vows to avenge them, even if it costs him the Parsathean crown. But when he learns it was the king’s daughter who lured his parents to their deaths, the barbarian warrior is determined to make her pay. Yet the woman Maddek captures is not what he expected. Though the last in a line of legendary warrior-queens, Yvenne is small and weak, and the sharpest weapons she wields are her mind and her tongue. Even more surprising is the marriage she proposes to unite them in their goals and to claim their thrones—because her desire for vengeance against her father burns even hotter than his own…

Book Description
Annie Caulfield's early years were spent by the seaside in Ireland. However, the family shifted to Sixties London and soon she wasn't sure who she was - was she English, was she Irish, and if so, what kind of Irish? Watching the news of The Troubles, she was unable to recognise the country she'd left behind. On return journeys to visit her family over the last thirty years, she discovers how much The Troubles have caused weird and successful aspects of the country's life and history to be overlooked. Caulfield's background is religiously and politically mixed, giving her a unique and often astute perspective on The Troubles. This is an Irish emigrant's tale, asking whether you can ever really go back to your roots. If you were a punk rocker when others were on hunger strike, can you really put your hand on your heart and say 'my people'? If you get a headache and go home to watch Big Brother on 12th July, are you just too flippant to understand your own country? There are many books on the recent history of Northern Ireland, but none give such a funny insight into the lives of ordinary people as Annie Caulfield's affectionate portrait of 'Alternative Ulster'.

Book Description
Although cardiac output is measured as the flow of blood from the left ventricle into the aorta, the system that controls cardiac output includes many other components besides the heart itself. The heart’s rate of output cannot exceed the rate of venous return to it, and therefore, the factors governing venous return are primarily responsible for control of output from the heart. Venous return is affected by its pressure gradient and resistance to flow throughout the vascular system. The pressure gradient for venous return is a function of several factors including the blood volume flowing through the system, the unstressed vascular volume of the circulatory system, its capacitance, mean systemic pressure, and right atrial pressure. Resistance to venous return is the sum of total vascular resistance from the aortic valve to the right atrium. The sympathetic nervous system and vasoactive circulating hormones affect short-term resistance, whereas local tissue blood flow autoregulatory mechanisms are the dominant determinants of long-term resistance to venous return. The strength of contraction of the heart responds to changes in atrial pressure driven by changes in venous return, with small changes in atrial pressure eliciting large changes in strength of contraction, as described by the Frank–Starling mechanism. In addition, the autonomic nervous system input to the heart alters myocardial pumping ability in response to cardiovascular challenges. The function of the cardiovascular system is strongly affected by the operation of the renal sodium excretion–body fluid volume–arterial pressure negative feedback system that maintains arterial blood pressure at a controlled value over long periods. The intent of this volume is to integrate the basic knowledge of these cardiovascular system components into an understanding of cardiac output regulation.
