  2. Alveolar lung disease - Wikipedia

    en.wikipedia.org/wiki/Alveolar_lung_disease

    Alveoli are the functional units of the lungs. Alveolar lung diseases are classified as processes that affect these units that ultimately lead to issues with ventilation. There are a number of different causes of insult to the alveoli including build up of fluid, hemorrhage, infection, malignancy and build up of protein and mineral deposi

  3. Diffuse alveolar damage - Wikipedia

    en.wikipedia.org/wiki/Diffuse_alveolar_damage

    Diffuse alveolar damage (DAD) is a histologic term used to describe specific changes that occur to the structure of the lungs during injury or disease.Most often DAD is described in association with the early stages of acute respiratory distress syndrome (). [1]

  4. Pulmonary alveolus - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_alveolus

    They are located sparsely in these bronchioles, line the walls of the alveolar ducts, and are more numerous in the blind-ended alveolar sacs. [5] The acini are the basic units of respiration, with gas exchange taking place in all the alveoli present. [6] The alveolar membrane is the gas exchange surface, surrounded by a network of capillaries.

  5. Eosinophilic pneumonia - Wikipedia

    en.wikipedia.org/wiki/Eosinophilic_pneumonia

    When eosinophilic pneumonia is related to an illness such as cancer or parasitic infection, treatment of the underlying cause is effective in resolving the lung disease. When due to acute or chronic eosinophilic pneumonia, however, treatment with corticosteroids results in a rapid, dramatic resolution of symptoms over the course of one or two days.

  6. Interstitial lung disease - Wikipedia

    en.wikipedia.org/wiki/Interstitial_lung_disease

    Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...

  7. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    The presence of emphysema is a clear risk factor for lung cancer, made stronger in those who smoke. [20] Early symptoms of emphysema vary. They can include a cough (with or without sputum), wheezing, a fast breathing rate, breathlessness on exertion, and a feeling of tightness in the chest. There may be frequent cold or flu infections. [1]

  8. Respiratory tract - Wikipedia

    en.wikipedia.org/wiki/Respiratory_tract

    alveolar duct. alveolar sac. alveolus; At each division point or generation, one airway branches into two smaller airways. The human respiratory tree may consist on average of 23 generations, while the respiratory tree of the mouse has up to 13 generations. Proximal divisions (those closest to the top of the tree, such as the bronchi) mainly ...

  9. Ventilation–perfusion coupling - Wikipedia

    en.wikipedia.org/wiki/Ventilation–perfusion...

    Within the lungs, the ventilation process specifically involves organs like respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli. For the perfusion process, the circulatory organs of the cardiovascular system such as the heart, pulmonary arteries, pulmonary veins, and alveolar capillaries are involved.
