    en.wikipedia.org/wiki/Breathing

    When warm, wet air from the lungs is breathed out through the nose, the cold hygroscopic mucus in the cool and dry nose re-captures some of the warmth and moisture from that exhaled air. In very cold weather the re-captured water may cause a "dripping nose". Ideally, air is breathed first out and secondly in through the nose. [9]

    en.wikipedia.org/wiki/Work_of_breathing

    The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...

  6. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The lungs expand and contract during the breathing cycle, drawing air in and out of the lungs. The volume of air moved in or out of the lungs under normal resting circumstances (the resting tidal volume of about 500 ml), and volumes moved during maximally forced inhalation and maximally forced exhalation are measured in humans by spirometry. [12]

  7. Respiratory adaptation - Wikipedia

    With higher intensity training, breathing rate is increased in order to allow more air to move in and out of the lungs, which enhances gas exchange. Endurance training typically results in an increase in the respiration rate. [4]
