water-vascular system

[ waw-ter-vas-kyuh-ler, wot-er- ]

Phonetic (Standard)IPA

noun

, Zoology.

a system of closed, fluid-filled tubes and ducts of echinoderms used in clinging, locomotion, feeding, and respiration.

First recorded in 1865–70

The diverticula from the alimentary cavity form the water-vascular system and the somatic and splanchnic layers of mesoblast.

The cavity of the diverticula after the separation of the water-vascular system, forms the body-cavity.

They have locomotor organs, the ambulacra, and a water-vascular system peculiar to themselves.

The tube-feet are in connection with a system of vessels filled with fluid, known as the Water-vascular System of the Starfish.

The Water-vascular System is a structure common to all Echinoderms; and vessels of a comparable character are found in some worms.
