lung
\lung\ (?), 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. &?; see light not heavy.] (anat.) an organ for aërial respiration; -- commonly in the plural. my lungs began to crow like chanticleer.
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.

Lung Definition from Encyclopedia Dictionaries & Glossaries
The lung is the essential respiration organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli.

Lung (Chinese) Dragon; the being who excels in intelligence. Dragons of Wisdom was the name given by the Chinese to the first disciples of the primitive adepts of the third root-race, and later of the fourth and fifth root-races. The dragon was described as: "gifted with an accepted form, which he has the supernatural power of casting off for the assumption of others, he has the power of influencing the weather, producing droughts or fertilizing rains at pleasure, of raising tempests and allaying them" (Mythical Monsters 212).
Confucius spoke of the dragon as one who "feeds in the pure water of Wisdom and sports in the clear waters of Life"; while the Twan-ying-tu says of the yellow dragon, "His wisdom and virtue are unfathomable . . . he does not go in company and does not live in herds (he is an ascetic). He wanders in the wilds beyond the heavens. He goes and comes, fulfilling the decree (Karma); at the proper seasons if there is perfection he comes forth, if not he remains (invisible)" (SD 2:365).
