Y1 - 2023 N1 - T2 - Fishman’s Pulmonary Diseases and Disorders, 6e AB - At the end of a deep breath, about 80% of the lung volume is air, 10% is blood, and only the remaining 10% is tissue*. Because this small mass of tissue is spread over an enormous area—nearly the size of a tennis court—the tissue framework of the lung must be extraordinarily delicate. It is indeed remarkable that the substance of the lung manages to maintain its integrity in the face of the multitude of insults that inevitably accompany a lifetime of exposure to ambient air and the complex necessity of keeping air and blood in intimate contact, but separate, for the sake of gas exchange.
