Webster's 1913 Dictionary
\Lung\, n. [OE. lunge, AS. lunge, pl. lungen; akin to D.

the root of E. light. ? See {Light} not heavy.] (Anat.)

      My lungs began to crow like chanticleer. --Shak.

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.

Dream Dictionary
 Definition: Seeing lungs in your dream, symbolize insight, creativity, and inspiration. Alternatively, lungs may indicate a stressful situation and refer to a relationship/situation in which you feel suffocated.
Biology Dictionary
 Definition: An organ found in air-breathing vertebrate animals which functions in air respiration. It transfers atmospheric oxygen from the air to the blood, and carbon dioxide and other waste gases from the blood to the air. Most animals have a pair; one species of lungfish has just one, and other primitive fish may have lunglike air bladders (the swim bladder, found in many bony fishes, evolved from the lung).
