Amphisbaenians, however, have the opposite arrangement, with a major left lung, and a reduced or absent right lung [WP] NCIT:C12468 MIAA:0000135 AAO:0000275 FMA:7195 XAO:0000119 pulmo BTO:0000763 EFO:0000934 MAT:0000135 UBERON:0002048 UMLS:C0024109 EHDAA2:0001042 MA:0000415 GAID:345 respiration organ in all 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 in the chest 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. // Avian lungs do not have alveoli as mammalian lungs do, they have Faveolar lungs. They contain millions of tiny passages known as para-bronchi, connected at both ends by the dorsobronchi Respiration organ that develops as an outpocketing of the esophagus. Lungs had already developed as paired ventral pockets from the intestine in the ancestor of Osteognathostomata. (...) In actinopterygian fishes, apart from Cladistia, the ventral intestinal pocket migrates dorsally and becomes the swim-bladder, a mainly hydrostatical organ (reference 1); Comparative transcriptome analyses indicate molecular homology of zebrafish swimbladder and Mammalian lung (reference 2).[well established][VHOG] CALOHA:TS-0568 Either of two organs which allow gas exchange absorbing oxygen from inhaled air and releasing carbon dioxide with exhaled air.[AAO] lung EV:0100042 AAO:0010567 EHDAA:2205 OpenCyc:Mx4rvVjKy5wpEbGdrcN5Y29ycA MESH:D008168 EHDAA:1554 endoderm-derived structure thoracic cavity element lateral structure
