• gills
  • hypothetical devices to allow a human to take in oxygen from surrounding water Artificial gills are unproven conceptualised devices to allow a human to be able to take in oxygen from surrounding water. (wikipedia.org)
  • Natural gills work because nearly all animals with gills are thermoconformers, so they need much less oxygen than a thermoregulator of the same size. (wikipedia.org)
  • processes
  • In recovery, oxygen (EPOC) is used in the processes that restore the body to a resting state and adapt it to the exercise just performed. (wikipedia.org)
  • vertebrates
  • Per unit volume, there is much more oxygen in air than in water, and vertebrates are active animals with a high energy requirement compared to invertebrates of similar sizes. (wikipedia.org)
  • concentration
  • At higher altitudes and in warmer climates the oxygen concentration in the air is lower compared to low altitude or colder climate. (wikipedia.org)

  • primarily
  • Further analysis of the ideal cycle indicated that the end-systolic P-V relationship (ESPVR) is an approximation to the adiabatic P-V trajectory that primarily determines total energy consumption. (biomedsearch.com)
  • effect
  • Both octanoic acid and oleic acid stimulated oxygen consumption to a similar degree during hypothermic perfusion suggesting that the detrimental effect of octanoic acid was due to direct metabolic stimulation rather than uncoupling of oxidatative phosphorylation. (wikipedia.org)
  • temperatures
  • Oxygen uptakes of Douglas-fir beetles collected during November 1969 through April 1970 were measured at different experimental temperatures. (oregonstate.edu)
  • levels
  • The Devonian saw increasing oxygen levels which opened up new ecological niches by allowing groups able to exploit the additional oxygen to develop into active, large-bodied animals. (wikipedia.org)
  • closed circuit
  • An average diver with a fully closed-circuit rebreather needs 1.5 liters of oxygen per minute while swimming or .64 liters per minute while resting. (wikipedia.org)
  • active
  • They are generally thought to be unwieldy and bulky, because of the massive amount of water that would have to be processed to extract enough oxygen to supply an active diver, as an alternative to a scuba set. (wikipedia.org)
  • Public
  • This was substantiated in 2016 by the $50,000 DiNenno Prize, which recognized oxygen consumption calorimetry as a significant technical achievement that has had a major impact on public safety. (wikipedia.org)
  • heat
  • During periods of flight, the cells require more oxygen, and the heat generated must be dissipated to avoid hyperthermia. (wikipedia.org)
