Science - Zoology
English term or phrase: coelom
Definition from ucmp.berkeley.edu:
Fluid-filled cavity within the body of an animal; usually refers to a cavity lined with specialized tissue peritoneum in which the gut is suspended. The structure and development of the coelom is an important character for recognizing major groups of animals.

Example sentence(s):
  • Simpler animals like cnidarians (jellyfish, coral, etc.) and sponges are diploblastic and monoblastic respectively, lacking a coelom. Though the coelom developed in triploblastic animals, some of these animals have lost their coeloms. wiseGEEK
  • Flatworms would have lost the coelom secondarily. Since their acoelomate condition is no longer indicative of a primitive origin, most of their characters put them in the protostomes, with the spiralian phyla. CBS Interactive Inc. BNET
  • Functionally, a coelom can absorb shock or provide a hydrostatic skeleton. nationmaster.com

Definition from http://translate.google.co.jp/translate?:
体腔 （ "シール発音-ええと" /市ː ləm 発音/ ）は、流体いっぱいの空洞の中胚葉内に形成されています。 Coeloms triploblasts が開発 、その後、いくつかの系統で失われた。 体腔の損失ボディサイズの減少と相関している。 Coeloms二胚葉動物の cnidariansなど欠席している 。

Example sentence(s):
  • 体腔（たいこう・たいくう）は、動物の外胚葉（体壁）と内胚葉（消化管）の間の空所であり、中胚葉性の組織（腹膜など）で裏打ちされたものである。空所はあるがこの裏打ちがない場合を偽体腔と呼び、真の体腔（真体腔）と区別する。例えば脊椎動物における腹膜腔、胸膜腔、囲心腔などが体腔であり、内胚葉由来の諸器官が収まっている。 - Dictionary & Translation by Babylon
