Final answer:
The correct order from outermost to innermost is: chest wall, parietal pleura, interpleural space, visceral pleura, and lungs. This arrangement facilitates the protection, pleural cavity maintenance, and proper lung function.
Step-by-step explanation:
Order of Lung Structures from Outermost to Innermost
The correct order from the outermost to the innermost structure is: B. chest wall, A. parietal pleura, D. interpleural space, C. visceral pleura, and E. lungs.
The chest wall is the outermost layer, providing protection and support for the thoracic cavity. The parietal pleura is the next layer which lines the interior of the thorax. The interpleural space is filled with a small amount of fluid that reduces friction between the pleural layers. The visceral pleura is directly superficial to the lungs and extends into lung fissures. Lastly, we have the lungs themselves which are the innermost structures.
