Gas exchange features
WebAt the gas exchange level, sheet-flow design preponderates in the evolved gas exchangers; blood is efficiently exposed to the external respiratory medium. The respiratory capacity of a gas exchanger is comprehensively granted by refinements of structural features and functional processes.

WebThe gas exchange surfaces are the alveoli. They are very efficient at gas exchange. They provide a large surface area relative to the volume of the body; Gasses dissolve in the surfactant moisture lining the alveoli; The alveoli have walls made of squamous epithelium, only one cell thick, so the diffusion pathway for gases is short WebJul 6, 2024 · Interstitial Lung Diseases (ILDs) are a large family of disorders characterized by inflammation and/or fibrosis of areas of the lung dedicated to gas exchange.
