In modern physiology, very simplified perceptions of such an essential system for the body as the respiratory system have taken root. The system analysis showed that at a physical load of more than 50 W, the tissue respiratory subsystem is activated, providing a volume blood flow rate adequate to the amount of oxygen consumed, and in the external respiratory subsystem the regulation on oxygen voltage in arterial blood is activated, and the regulation on carbon dioxide voltage is deactivated. The role of respiratory frequency in increasing the rate of diffusion through the alveolar capillary membrane is shown. For physiologists, medical professionals and trainers.

Alveolar Capillary

The pathway of oxygen through the body consists of the diffusion of oxygen across the alveolar-capillary membrane and then the peripheral tissue membranes, followed by the convective transport of oxygen in the blood. Any transport process will have its choke points and limitations. In the case of oxygen, the constraints can take 1 of 2 forms, perfusion limitation or diffusion limitation.

We measured arterial blood Po2, Pco2 and pH at rest and during a standard exercise test on a bicycle ergometer in ten normal subjects. In five we measured esophageal and five arterial blood temperature during the exercise and corrected the arterial blood values to the temperature at the time the samples were collected. We found an average rise in temperature of 1 C (range 0.2–1.6 C) during exercise lasting about 30 min at loads up to an average of 1,200 kg-m/min. At the highest load the average correction for PaOO2 was 5.6 mm Hg, for PaCOCO2 1.6 mm Hg and for pH 0.014 units. Our corrected values showed a fall in PaCOCO2 and pH and a rise in PaOO2 during severe exercise. These findings are compatible with the development of a metabolic acidosis during severe exercise and indicate that our subjects were not limited by diffusion across the alveolar-capillary membrane. metabolic acidosis; alveolar capillary membrane diffusion; hyperventilation; PaOO2 and PaCOCO2 in severe exercise Submitted on June 17, 1963

Front-line police operations are deeply entwined with less visible activities – or practices not commonly identified as policing – that are carried out by a wide range of participants as strategies of settler-colonial pacification operating through the organizing logics of security and liberal legalism. Using open source texts and records obtained through access to information requests, this article unmaps some of the contemporary strategies employed by Canadian institutions to pacify Indigenous resistance. As a contribution to the body of work seeking to develop the politics of anti-security, the analysis disrupts the binary categories that animate security logic by examining the public order policing approach of the Ontario Provincial Police, the framing of Indigenous resistance as a security threat, and the integral role of Indian Affairs in securing the settler-state.

How can we be aware of ourselves both as physical objects and as thinking, experiencing subjects? What role does the experience of the body play in generating our sense of self? What is the role of action and agency in the construction of the bodily self? These questions have been a rich subject of interdisciplinary debate among philosophers, neuroscientists, experimental psychologists, and cognitive scientists for several decades. José Luis Bermúdez been a significant contributor to these debates since the 1990’s, when he authored The Paradox of Self-Consciousness (MIT Press, 1998) and co-edited The Body and the Self (MIT Press, 1995) with Anthony Marcel and Naomi Eilan. The Bodily Self is a selection of essays all focused on different aspects of the role of the body in self-consciousness, prefaced by a substantial introduction outlining common themes across the essays. The essays have been published in a wide range of journals and edited volumes. Putting them together brings out a wide-ranging, thematically consistent perspective on a set of topics and problems that remain firmly of interest across the cognitive and behavioral sciences.

The CO diffusing capacity (Dl) was measured by the single-breath method in eight anesthetized dogs. Pulmonary capillary blood volume (Vc) and membrane diffusing capacity (Dm) were determined in six animals by the method of Roughton and Forster. The studies were repeated after anemia had been induced by replacing whole blood with plasma. Large dogs were selected with a mean body weight of 29 kg and a mean alveolar volume of 2,020 ml (STPD) during tests. The mean arterial blood Hb decreased from 14.3 to 6.6 g/100 ml, the mean Dl from 27 to 12 ml/min mm Hg, and the mean Dm from 100 to 47 ml/min mm Hg. Vc averaged 67 ml in the control state and was not significantly changed during anemia. Reductions in Dl and Dm during anemia were proportional to the fall in blood Hb. Both Dl and Dm in all dogs, normal and anemic, were proportional to the volume of red blood cells in the lung capillaries (Vrbc). These results suggest that Vrbc might be an estimate of the useful area of the alveolar-capillary membrane while Dm/Vrbc should vary with changes in its thickness. The latter was not altered by anemia. alveolar capillary membrane; pulmonary membrane; diffusing capacity; pulmonary capillary RBC volume; pulmonary diffusion pathway; carbon monoxide Submitted on March 2, 1964

✓ Spinal cord blood flow (SCBF) was measured over a wide range of artificially varied mean systemic arterial blood pressures (MAP) in a group of monkeys with alpha adrenergic receptors blocked by the intravenous administration of phenoxybenzamine (Dibenzyline). The SCBF was found to vary linearly with changes in MAP. Autoregulation appeared to have been abolished. These data are cited as evidence for a dominant role of the sympathetic nervous system in control of the spinal circulation.

Equal Interest

The relationship between language and the body has become an increasingly prominent area of research within linguistics and related disciplines. Some investigators of this question have examined how facts about the human body are encoded in linguistic structure, while others have explored the use of the body as a communicative resource in interaction. Surprisingly little, however, has been written about the role of language in constructing the body as a social object. In Fat talk, Mimi Nichter, a medical anthropologist, addresses this issue by examining the discourse of dieting among American teenage girls. Although language itself is not the center of the analysis, Nichter draws on a wide range of sociolinguistic research to investigate how the body is constructed through talk – a question that will be of equal interest to scholars of language, culture, and society.

Aortic Obstruction

In anesthetized dogs, bleeding (1.5–3% of the body weight) was allowed while renal arterial pressure was maintained at constant levels by graded changes of mechanical aortic obstruction. The renal hematocrit decreased, (as measured with I131 albumin and acid hematin, and as compared to the blood hematocrit), primarily as a result of an increased renal plasma volume. These changes are correlated with previously identified alterations of sodium excretion, all independent of renal innervation or arterial blood pressure. It is proposed that hemorrhage may involve an intrarenal redistribution of blood flow favoring diversion of plasma to cell-poor capillaries or to lymphatic spaces.
