Lung fever
(gcide) | Lung \Lung\ (l[u^]ng), n. [OE. lunge, AS. lunge, pl. lungen;
akin to D. long, G. lunge, Icel. & Sw. lunga, Dan. lunge, all
prob. from the root of E. light. [root]125. See Light not
heavy.] (Anat.)
An organ for a["e]rial respiration; -- commonly in the
plural.
[1913 Webster]
My lungs began to crow
like chanticleer. --Shak.
[1913 Webster]
Note: In all air-breathing vertebrates the lungs are
developed from the ventral wall of the esophagus as a
pouch which divides into two sacs. In amphibians and
many reptiles the lungs retain very nearly this
primitive saclike character, but in the higher forms
the connection with the esophagus becomes elongated
into the windpipe and the inner walls of the sacs
become more and more divided, until, in the mammals,
the air spaces become minutely divided into tubes
ending in small air cells, in the walls of which the
blood circulates in a fine network of capillaries. In
mammals the lungs are more or less divided into lobes,
and each lung occupies a separate cavity in the thorax.
See Respiration.
