On Oxygen: From Air to Tissues, the latest release in the Fundamentals of Physiology series, provides a fundamental overview of the entire oxygen pathway, sharing key mechanistic insights into the alternating conductive and diffusive steps of O2 transport. The book describes specific aspects along each stage of the oxygen route through the body, from the transfer of air to the alveoli, through the lungs, to the ultimate fate of O2 in the mitochondria. Additionally, the effect of specific disease states, aging, and developmental aspects are considered.This book, published in association with the International Union of Physiological Sciences, acts is a valuable introduction to the full biological journey of oxygen, and is a beneficial guide for students and researchers in physiology, sport science, pulmonology, and related fields. - Offers a comprehensive, integrated overview of oxygen delivery systems from air to cell and its impact on physiological function - Covers fundamental aspects of each stage of oxygenation, providing a reductionist approach to complex topics - Explores physiological responses in the human body at rest and during exercise - Includes case studies considering various mammals, terrestrial vertebrates, and aquatic animals in discussion of how body size influences key elements of the O2 transport chain
