The water vascular system of echinoderms . The water vascular system of echinoderms . is analogous to the gastrovascular cavity of flatworms functions as a circulatory system that distributes nutrients to body cells is bilateral in organization, even though the adult animal is not bilaterally symmetrical functions in locomotion and feeding

Details about water vascular system of echinoderms is described below.

Explanation:

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 system is composed of canals connecting numerous tube feet.The water vascular system of echinoderms is essentially a system of fluid-filled canals that extend along each of the body regions and have many external projections called tube feet. There are several functions of the system, one of which is to use water pressure to mediate movement and assist in feeding.They move using the a hydraulic system called the water vascular system. Jellyfish, hydra, coral, and sea anemones belong to phylum Cnidaria. Cnidarians have radial symmetry, tentacles, and two layers of tissue surrounding a central "stomach" cavity. They also have one digestive opening and a nerve network.Echinoderms do not have a true circulatory system like the ones found in humans or other mammals. ... Their blood and fluids are pumped around their body by their water vascular system, which is found in all echinoderms.The madreporite is an essential part of the circulation system in echinoderms. Through this plate, which is also called a sieve plate, the echinoderm draws in seawater and expels water to fuel its vascular system. The madreporite functions like a trap door through which water can move in and out in a controlled mannerThe 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.
