Water vascular system Wikipedia
Starfish have a well structured system of tubes that works in place of the circulatory system. Sand dollar Circulatory System The sand dollar does not have a circulatory, respiratory, or excretory systems, It has a network of water-filled canals called the water vascular system to help move & feed.... All echinoderms have a unique system of internal tubes called a water vascular system. The water vascular system opens to the outside through a sievelike structure called the madreporite (ma-druh-POR-ight). In starfish, the madreporite connects to a tube called the ring canal that forms a circle around the animal's digestive system. From the ring canal, five radial canals extend into each body

Explain the water's path in a starfish's water vascular
The water vascular system starts with the madreporite and gives off a system of vessels traversing the body. The madeporite is a round calcareous plate (Fig. 21.7B) and has an inter-radial disposition on the aboral surface. The madreporite contains furrows which have numerous pores at the bottom. Each pore leads into a pore canal. database management system dbms pdf Echinoderms Mollusks, Pentaradial Symmetry, Water Vascular System, Tube Feet, Ampulla, Endoskeleton, Pedicellariae, Class Crinoidea, Subclass Asteroidea, Subclass Ophiuroidea.
