  2. Thoracic diaphragm - Wikipedia

    en.wikipedia.org/wiki/Thoracic_diaphragm

    The diaphragm is the main muscle of respiration and functions in breathing. During inhalation, the diaphragm contracts and moves in the inferior direction, enlarging the volume of the thoracic cavity and reducing intra-thoracic pressure (the external intercostal muscles also participate in this enlargement), forcing the lungs to expand. In ...

  3. Muscles of respiration - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_respiration

    The diaphragm is the major muscle responsible for breathing. It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward).

  4. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The alveolar air pressure is therefore always close to atmospheric air pressure (about 100 kPa at sea level) at rest, with the pressure gradients because of lungs contraction and expansion cause air to move in and out of the lungs during breathing rarely exceeding 2–3 kPa. [18] [19] During exhalation, the diaphragm and intercostal muscles relax.

  5. Diaphragmatic breathing - Wikipedia

    en.wikipedia.org/wiki/Diaphragmatic_breathing

    Air enters the lungs as the diaphragm strongly contracts, but unlike during traditional relaxed breathing the intercostal muscles of the chest do minimal work in this process. The belly also expands during this type of breathing to make room for the contraction of the diaphragm. [3]

    Real-time magnetic resonance imaging of the human thorax during breathing X-ray video of a female American alligator while breathing. Breathing (spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

  7. Diaphragmatic excursion - Wikipedia

    en.wikipedia.org/wiki/Diaphragmatic_excursion

    Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing. Normal diaphragmatic excursion should be 3–5 cm, but can be increased in well-conditioned persons to 7–8 cm. This measures the contraction of the diaphragm. It is performed by asking the patient to exhale and hold it.

    Diaphragmatic or abdominal breathing is a popular somatic exercise that can be done on its own or during other movements, such as walking or yoga, says Jurisson.

  9. Control of ventilation - Wikipedia

    en.wikipedia.org/wiki/Control_of_ventilation

    Breathing is normally an unconscious, involuntary, automatic process. The pattern of motor stimuli during breathing can be divided into an inhalation stage and an exhalation stage. Inhalation shows a sudden, ramped increase in motor discharge to the respiratory muscles (and the pharyngeal constrictor muscles). [5]
