1. Elastic recoil, size of the perfused surface for gas exchange and flow resistance of the small airways influence the symptomatology and lung function of pulmonary emphysema independently of each other. 2. The loss of elastic force and surface for gas exchange are predominant in panlobular emphysema. Ventilation-perfusion disturbances due to increased airway resistance during inspiration and expiration predominate in chronic obstructive bronchitis with centrilobular emphysema. 3. In the presence of identical values for vital capacity and FEV1.0, arterial blood gas studies during rest and exercise provide the most reliable information on gas exchange surface and ventilation-perfusion disorders.

UI	MeSH Term	Description	Entries
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.
