Which phylum uses a water vascular system?

phylum Echinodermata
The water vascular system is found in the phylum Echinodermata. The water vascular system is a hydraulic system that is used for locomotion, respiration, and food and waste transportation. It has canals which are connected to numerous tube feet to push the organisms against the ground.

What are 5 examples of echinoderms?

The phylum echinoderms is divided into five extant classes: Asteroidea (sea stars), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), Crinoidea (sea lilies or feather stars), and Holothuroidea (sea cucumbers).

Which animal possesses a water vascular system?

Animals belonging to the phylum Echinodermata possess a water vascular system. Sea cucumber, being an echinoderm, has a water vascular system. This water vascular system is involved in locomotion, respiration, and food and waste transportation.

Do flatworms have a water vascular system?

Flatworms lack a respiratory or circulatory system; these functions take place by absorption through the body wall. Nonparasitic forms have a simple, incomplete gut; even this is lacking in many parasitic species. Movement in some flatworms is controlled by longitudinal, circular, and oblique layers of muscle.

How does an echinoderm use its water vascular system?

Instead of blood, echinoderms have a water vascular system, which is used for movement and predation. The echinoderm pumps sea water into its body through a sieve plate or madreporite, and this water fills the echinoderm’s tube feet.

How does water enter the water vascular system of echinoderms?

The components of the water vascular system of echinoderms. Water enters the system through the madreporite, flows through the stone canal, and enters the ring canal. A number of bulbous structures, called polian vesicles, that branch off of the ring canal serve as reservoirs to maintain extra water stores.

What is vascular system in echinoderms?

Water vascular system 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.

What are the four groups of echinoderms?

Echinoderms are classified into the following five groups. They are Asteroidea (starfish, sea stars), Ophiuroidea (brittle stars), Echinoidea (Sea Urchins), Crinoidea (Feather Stars), and Holothuroidea (Sea Cucumbers). To know briefly about the each classification move on to the page Classification of Echinoderms.
