• Respiration
  • While the gills are thought to serve a respiratory function, respiratory demands are low in these mostly inactive animals, and, since the body and mantle are both bathed in water, respiration probably takes place across these surfaces as well. (britannica.com)
  • Respiratory acclimatization in humans is achieved through mechanisms that heighten the partial pressure of oxygen at all stages, from the alveolar spaces in the lung to the mitochondria in the cells , where oxygen is needed for the ultimate biochemical expression of respiration. (britannica.com)
  • Tiny hairs called cilia protect the nasal passage ways from dust, dirt or other particles.The Respiration System is where people exchange oxygen from the environment of Carbon Dioxide.As air is inhaled the cilia move back and forth pushing any particles toward the nostrils to get the dust out when exhaling.

  • breaths
  • This vital system of the body has many functions including olfaction detection, vocalization production, behavioral cues, filtration and humidification of inhaled breaths, and of course gas exchange. (springer.com)
  • During vigorous inhalation (at rates exceeding 35 breaths per minute), or when approaching respiratory failure, other accessory muscles are recruited for support. (newworldencyclopedia.org)
  • adult
  • Spread flat, the average adult male's respiratory surface would be about 750 sq ft (70 m 2 ), approximately the size of a handball court. (faqs.org)
