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.

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.

The history and evolution of the fields of science and medicine are symbiotically linked and thus are mutually dependent. Discoveries in one domain have allowed for progress in the other, and it is nearly impossible to study one area in isolation. The influence of science and technologic discoveries on medicine has profoundly impacted the way physicians practice and has resulted in an extended life expectancy and quality of life that our ancestors never dreamed possible. Science and Technology in Medicine is a collection of 99 essays based on landmark publications that have appeared in the medical literature over the past 500 years. Each essay includes a summary of the article or chapter; text and images reproduced directly from the original source; a short biography of the author(s); and a discussion about the significance of the discovery and its subsequent influence on later developments. Original material by the likes of Dürer, Bernoulli, Doppler, Pasteur, Trendelenburg, Curie and Röntgen offers readers a rare glimpse at publications housed in archives around the world, beautifully reproduced in one fascinating volume.
