“coelom”的概念、定义、翻译、参考文献-科学参考

coelom

Biology

A fluid-filled cavity that forms the main body cavity of vertebrate and most invertebrate animals. It is formed by the splitting of the mesoderm. Ciliated ducts (coelomoducts) connect the coelom to the exterior allowing the exit of waste products and gametes; in higher animals these are specialized as oviducts, etc. The coelom is large and often subdivided in annelid worms (in which it functions as a hydrostatic skeleton) and vertebrates. In arthropods it is restricted to the cavities of the gonads and excretory organs, the body cavity being a blood-filled haemocoel.

Geology and Earth Sciences

Principal body cavity in most animals, forming the cavity around the gut in many Annelida, and in Echinodermata and Vertebrata. In Arthropoda and Mollusca, the main body cavity is an expanded part of the blood system (a haemocoel) and the coelom is small.
