Thorax
Definition:
(n.) The part of the trunk between the neck and the abdomen, containing that part of the body cavity the walls of which are supported by the dorsal vertebrae, the ribs, and the sternum, and which the heart and lungs are situated; the chest.
(n.) The middle region of the body of an insect, or that region which bears the legs and wings. It is composed of three united somites, each of which is composed of several distinct parts. See Illust. in Appendix. and Illust. of Coleoptera.
(n.) The second, or middle, region of the body of a crustacean, arachnid, or other articulate animal. In the case of decapod Crustacea, some writers include under the term thorax only the three segments bearing the maxillipeds; others include also the five segments bearing the legs. See Illust. in Appendix.
(n.) A breastplate, cuirass, or corselet; especially, the breastplate worn by the ancient Greeks.
Example Sentences:

(2) We measured the steady-state volumes of distribution for radioactive chloride, sucrose, and albumin in the lung of six anesthetized, spen-thorax sheep.
(3) ELS (or accessory lungs) is a rare congenital abnormality defined as a lung segment outside a normal lung, usually localized in the left lower thorax.
(4) Respiratory failure, developing 7-9 days after inoculation, was associated with a decrease in lung-thorax compliance determined during artificial ventilation, and an increase in the amount of protein including the specific antibody in lung lavage fluid.
