Download or read book Upper Body Venous Compliance Exceeds Lower Body Venous Compliance in Humans written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-15 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human venous compliance hypothetically decreases from upper to lower body as a mechanism for maintenance of the hydrostatic indifference level 'headward' in the body, near the heart. This maintains cardiac filling pressure, and thus cardiac output and cerebral perfusion, during orthostasis. This project entailed four steps. First, acute whole-body tilting was employed to alter human calf and neck venous volumes. Subjects were tilted on a tilt table equipped with a footplate as follows: 90 deg, 53 deg, 30 deg, 12 deg, O deg, -6 deg, -12 deg, -6 deg, O deg, 12 deg, 30 deg, 53 deg, and 90 deg. Tilt angles were held for 30 sec each, with 10 sec transitions between angles. Neck volume increased and calf volume decreased during head-down tilting, and the opposite occurred during head-up tilt. Second, I sought to cross-validate Katkov and Chestukhin's (1980) measurements of human leg and neck venous pressures during whole-body tilting, so that those data could be used with volume data from the present study to calculate calf and neck venous compliance (compliance = (Delta)volume/(Delta)pressure). Direct measurements of venous pressures during postural chances and whole-body tilting confirmed that the local changes in venous pressures seen by Katkov and Chestukhin (1980) are valid. The present data also confirmed that gravitational changes in calf venous pressure substantially exceed those changes in upper body venous pressure. Third, the volume and pressure data above were used to find that human neck venous compliance exceeds calf venous compliance by a factor of 6, thereby upholding the primary hypothesis. Also, calf and neck venous compliance correlated significantly with each other (r(exp 2) = 0.56). Fourth, I wished to determine whether human calf muscle activation during head-up tilt reduces calf venous compliance. Findings from tilting and from supine assessments of relaxed calf venous compliance were similar, indicating that tilt-induced muscle activation is relati...

Download or read book Control of Cardiac Output written by David Young and published by Biota Publishing. This book was released on 2010-01-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Adaptation Biology and Medicine written by Y Kawai and published by ALPHA SCIENCE INTERNATIONAL LIMITED. This book was released on 2017-01-05 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the entire evolution of life is an adaptation right from the coming-together of the elements and reaching to human life as we know today, the realization of the adaptation biology as a discipline is relatively recent. Furthermore, subcellular basis of gradual adaptation of body systems in stressful conditions is still a greate mystery of biology. The present book attempts to fill that gap. It is known that such an adaptation not only increases tolerance of the body to that given stress but also to other challenges. A complete knowledge of this cross protection needs to be defined and exp;oited to improve patient care. The book includes chapters describing subcellular adaptations; adaptation to different stresses as well as to lifestyle and environment. Although for an easy reading the information has been grouped under the sub-heading: Current Trends, the book represents a common continuum of adaptations. The therapeutic value of the understanding of the science of adaptation has also been described in several chapters. Examples of cross adaptations are also provided, where repeated exposure to one stinulus may ptentialyy be used in the treatment as well as prophylaxis of different diseases.The present book will be of great interest to all biologists, physiologists, pharmacologists and physicians interested in the application of the biology of adaptation in the improvement of health.
