➡️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.
➡️The valves located at the opening of the lateral canals into the tube feet also have an important function in the water vascular system of asteroids.
➡️They move by alternately contracting muscles that force water into the tube feet, causing them to extend and push against the ground, then relaxing to allow the feet to retract.
➡️ One of numerous extensions of an echinoderms water vascular system. Function in locomotion and feeding.
➡️The water vascular system is a modified part of coelom & consists of a system of sea water filled canals having certain corpuscles
