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
National bestselling author Juliet Marillier revisits the classic fairy tale of Beauty and the Beast in this “engaging Gaelic fantasy romance staring two fascinating reluctant souls”(Genre Go Round Reviews). Whistling Tor is a place of secrets, a mysterious, wooded hill housing the crumbling fortress belonging to Anluan—a chieftain whose name is spoken throughout the region in tones of revulsion and bitterness. A curse lies over Anluan’s family and his people, and the woods themselves hold a perilous force whose every whisper threatens doom. Then the young scribe Caitrin appears in Anluan’s garden, admiring the rare plant known as heart’s blood. Retained to sort through entangled family documents, Caitrin brings about unexpected changes in the household, casting a hopeful light against the despairing shadows. But even as Caitrin brings solace to Anluan, and the promise of something more between them, he remains in thrall to the darkness surrounding Whistling Tor. To free Anluan’s burdened soul, Caitrin must unravel the web of sorcery woven by his ancestors before it claims his life—and their love...

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…
