Atelectasis is the partial collapse or closure of a lung resulting in reduced or absent gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
The membrane between alveoli and capillaries is torn; damage to this capillary–alveolar membrane and small blood vessels causes blood and fluids to leak into the alveoli and the interstitial space (the space surrounding cells) of the lung. [11] With more severe trauma, there is a greater amount of edema, bleeding, and tearing of the alveoli. [17]
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 deposits.

The alveolar capillary specifically participates in perfusion to get in contact with the alveoli for the gas exchange and oxygen delivery to the body tissues.
