     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}.
