Water Vascular System In Echinoderms

The water vascular system is present in the organisms which belong to the group of Echinoderms. Cell dedifferentiation and migration are accompanied by mitotic divisions. It comprises an internal hydraulic system of canals and reservoirs containing a watery fluid the system consisting of a sieve plate or madreporite and a. Water vascular system or Ambulacral system is a peculiar system which is seen in only Echinoderms. The system is a hydraulic system. By expanding and contracting chambers within the water vascular system the echinoderm can. Physiological Processes of Echinoderms.

This system is well developed in Asteroidea.

The network contains a central ring and areas which contain the tube feet which stretch along the body or arms. It is filled with sea water it is called water vascular system or Ambulacral system. Echinoderms move by alternately contracting muscles that force water into it is restricted to water channels in. These are called tube feet or podia and are filled with sea water in most echinoderms. General Plan of Water Vascular System A basic plan of the system chiefly comprises of following components. The water vascular system is a hydraulic system used by echinoderms such as sea stars and sea urchins for locomotion food and waste transportation and respiration.
