原始的肺只不过是一个气囊，气囊壁上有用于气体交换的微小血管。它作为一种辅助呼吸器官，使鱼类能够从缺氧的沃茨中寻求庇护，在陆地上作为空气呼吸器生存。1，2随着时间的推移，随着最初离开水的鱼类被几代在陆地上生活的脊椎动物所取代，肺变得更加复杂。不仅气体交换的解剖结构变得更加复杂，而且其他专业化-其中一些只是间接与气体交换有关-变得明显。在. . ... .
THE primitive lung was little more than an air sac containing minute vessels in its walls for gas exchange. It served as an accessory organ of breathing that allowed fishes seeking refuge from oxygen-poor waters to survive on land as air breathers.1,2In the course of time, as the original fishes out of water were succeeded by generations of vertebrates that were at home on land, the lung grew more complicated. Not only did anatomic arrangements for gas exchange grow more intricate, but additional specializations — some of which were only indirectly related to gas exchange — became evident. Among . . .
