Water enters the system through the sieve plate, and then flows through the ring canal around the mouth. From the ring canal the water flows through the radial canal in the feet. The radial canal is connected to the tube feet which has hundreds of tiny suckers. Oxygen enters and waste leaves the tube feet. Each tube foot is connected to an ampulla. The ampulla regulates fluid pressure so that each tube foot may extend or retract, hang on or let go.

What is vascular system?
A plant's vascular system consists of vascular tissue. The vascular tissue is made up of xylem (transports water) and the phloem (transports sugars and other nutrients). Another component of the vascular system is the meristems: the vascular meristem and the cork cambium, both of which are sites of growth.
What is water vascular system and its general structure and function?
The water vascular system is a hydraulic system used by echinoderms, such as starfish and sea urchins, for locomotion, food and waste transportation, and respiration.
