    Lung - Wikipedia

    https://en.wikipedia.org/wiki/Lung

    The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen … See more

    Structure

    Anatomy
    The lungs are located in the chest on either side of the heart in the rib cage. They are conical in shape with a narrow rounded apex at the top, and a broad concave base that rests on the … See more

    Development

    The development of the human lungs arise from the laryngotracheal groove and develop to maturity over several weeks in the foetus and for several years following birth.
    The larynx, trachea, bronchi and lungs that make up the … See more

    Gene and protein expression

    About 20,000 protein coding genes are expressed in human cells and almost 75% of these genes are expressed in the normal lung. A little … See more

    Birds
    The lungs of birds are relatively small, but are connected to 8 or 9 air sacs that extend through much of the body, and are in turn connected to air spaces within the bones. On inhalation, air travels through the trachea of a bird … See more

    Microanatomy

    The lungs are part of the lower respiratory tract, and accommodate the bronchial airways when they branch from the trachea. The bronchial airways terminate in alveoli which make up the functional tissue (parenchyma) of the lung, and veins, arteries, nerves, and See more

    Function

    Gas exchange
    The major function of the lungs is gas exchange between the lungs and the blood. The alveolar and pulmonary capillary gases equilibrate across the thin blood–air barrier. This thin membrane (about 0.5 –2 μm thick) is folded … See more

    Clinical significance

    Lungs can be affected by a number of diseases and disorders. Pulmonology is the medical speciality that deals with respiratory diseases involving the lungs and respiratory system. Cardiothoracic surgery deals with surgery of the lungs including See more

    • Lung volumes - Wikipedia

      https://en.wikipedia.org/wiki/Lung_volumes

      Lung volumes and lung capacities refer to the volume of air in the lungs at different phases of the respiratory cycle.
      The average total lung capacity of an adult human male is about 6 litres of air.
      Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.

      • IC: Inspiratory capacity: the sum of IRV and TV
      • RV: Residual volume: the volume of air remaining in the lungs after a maximal exhalation
      • IRV: Inspiratory reserve volume: the maximal volume that can be inhaled from the end-inspiratory level
      • TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV.
