• 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)

  • In: Bicher H.I., Bruley D.F. (eds) Oxygen Transport to Tissue-IV. (springer.com)
  • Duration
  • Breath-hold duration is limited by oxygen reserves, and the risk of hypoxic blackout, which has a high associated risk of drowning. (wikipedia.org)
  • less
  • A person that is more fit will be able to consume the same amount of oxygen with fewer heartbeats than a less fit person. (zanran.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)
  • amount
  • 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)
  • energy
  • This acceleration of oxygen consumption is presumably due to either an increased energy requirement (for either accelerated synthesis or catabolism) or an uncoupling of oxidative phosphorylation. (ahajournals.org)
