Besides the exchange of oxygen and carbon dioxide with the environment, an important role of the respiratory tract is, during inspiration, to heat the air to body temperature and to saturate it with water, before it reaches the alveoli. This is physiologically crucial because it protects the alv...
Oxygen uptake and carbon dioxide release at 28°C were determined in worker castes of twenty-six species of forest termites from the Danum Valley Conservation Area, south-east Sabah, by Warburg manometry. Metabolic rate varied inversely with body weight in a suite of soil-, wood/soil- and ...
7.Oxygen isotope exchange between water and carbon dioxide in soils is controlled by pH, nitrate and microbial biomass through links to carbonic anhydrase activity and spring 机译:土壤中的水和二氧化碳之间的氧同位素交换通过pH,硝酸盐和微生物生物量来控制通过与碳酸酐酶活性的链接来控制 Sam P. Jones ...
FEW, if any, really simple methods have been proposed for the simultaneous estimation of the carbon dioxide evolution and oxygen uptake of living tissues in which it is possible to maintain the composition of the gas mixture surrounding the tissue constant, and at the same time detect a rapid ...
Monitoring included ECG, pulse oximetry, invasive arterial pressure, temperature, end-tidal carbon dioxide, oxygen and xenon concentrations. All intraoperative continuous variables were recorded every 3 min. Arterial blood gas analysis was per- formed in the preoperative assessment, at 15 ...
A Passive Model of the Heat, Oxygen and Carbon Dioxide Transport in the Human Body The aim of this work is the development of a mathematical model which integrates a model of the human respiratory system and a model of the human thermal s... C Albuquerque-Neto,JI Yanagihara 被引量: 5发...

3. A method according to claims 1 or 2, characterized in that the oxygen and the carbon dioxide contents of the gas in the container (5) are measured. 4. A method according to any of the claims 1-3 above, characterized in that the volume of the gas in the container (5) is calcu...
Total and cutaneous O 2 and CO 2 exchanges were studied in the unanesthetized, spinalectomized dogfish, Scyliorhinus canicula. Total oxygen uptake and carbon dioxide output were measured with an open flow respirometer. Cutaneous fluxes of O 2 and CO 2 were determined on the tail, confined in...
He left his indelible mark on the dark reactions of CAM with the words "The positive contribution made by the Leipzig workers was to draw attention to the possible cardinal importance (cf. Gustafson's qualified statement) of carbon dioxide rather than oxygen in controlling diurnal fluctuations in...
