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.

A Heart of Blood and Ashes
Author: Milla Vane
Publisher: Penguin
ISBN: 0440000513
Category : Fiction
Languages : en
Pages : 562
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…

How Tobacco Smoke Causes Disease
Author: United States. Public Health Service. Office of the Surgeon General
Publisher:
ISBN:
Category : Government publications
Languages : en
Pages : 728
Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
