Shak.
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.
