Message definition (Circulatory system)
The circulatory systems of all vertebrates, as well as of [[annelid]]s (for example, [[earthworm]]s) and [[cephalopod]]s ([[squid]]s, [[octopus]]es and relatives) always keep their circulating blood enclosed within heart chambers or blood vessels and are classified as ''closed'', just as in humans. Still, the systems of [[fish]], [[amphibian]]s, [[reptile]]s, and [[bird]]s show various stages of the [[evolution]] of the circulatory system. Closed systems permit blood to be directed to the organs that require it.

すべての脊椎動物、環形動物(たとえばミミズ)、頭足類(イカタコ、およびその近縁種)の循環体は、循環血液を常に心室や血管内に封じ込め、人間と同じように閉鎖系に分類される。それでも、魚類両生類爬虫類鳥類のシステムは、循環系の進化のさまざまな段階を示している。閉鎖系は、血液を必要とする臓器に血液を送ることができる。
