WebThe aim of this report is to outline the mechanisms and the adjustments of gas exchange and transport systems in vertebrates, using models suitable for quantitative analysis. A generalized and highly simplified scheme of the gas exchange and transport system is depicted in Fig. 1. The elements of the gas transport chain are ventilation, WebA trumpet model incorporating gas-phase axial diffusion was adapted to, for the first time, predict the gas exchange dynamics of carbon monoxide in the airways and alveoli. Simulated single-exhalation profiles were found in good agreement with measured healthy non-smoker expirograms for different exhalation flow rates and breath-holding.
