What are the structures of the water vascular system?
The structures of the water vascular system include a madreporite, stone canal, water pores, radial canals, lateral canals, tube feet, and ampullae. The madreporite is a porous, limy disc that functions as an external opening for the system, allowing water to enter. The stone canal is the sheltered passage that connects the madreporite to the body of the starfish. Water pores act as tiny openings along the sides of the stone canal that allow water to pass into the radial canals. The radial canals are a series of branching canals that run outward from the madreporite and supply the tube feet with water. Lateral canals connect the radial canals and extend to the periphery of the body, providing the tube feet with water. Tube feet are finger-like structures that use the pressure of water to extend, clinging to substrates and aiding in the starfish’s movement. Each tube foot is connected to an ampulla, a bulbous chamber on the animal’s body that acts as a reservoir for the water.
