Which group of invertebrates have a water vascular system and tube feet?
Echinodermates possess a water vascular system.
What is the body system for spines in Echinoderms?
water vascular system
How does water enter the water vascular system of echinoderms?
through the tube feet
Which group of invertebrates have a water vascular system tube feet?
Echinoderms :)
Liquid that fills an echinoderms vascular system?
When studying living creatures, it is important to know the details of their lives. Water is the liquid that fills an echinoderms vascular system.
System that allows echinoderms to move eat and breathe?
Echinoderms do not have a respiratory system similar to a person's. Instead, they have a water vascular (otherwise known as "ambulacral") system, made up of a network of canals to move water. This method accounts for the creature's gas exchange, feeding, and locomotion. Because of this characteristic, echinoderms lack gill slits.
Is circulation in echinoderms open or closed?
Closed. It also has a water-vascular system. :)
Why are echinoderms animals?
Echinoderms, such as starfish, have basal nerve ganglia that serve as a nervous system. They also have a water vascular system that acts as a circulatory system. They can reproduce, move, and digest food. Therefore, they are animals.
What structure is part of an echinoderms water vascular system?
The madreporite is the structure that is part of an echinoderm's water vascular system. It acts as a sievelike structure that allows water to enter the system and is connected to the internal canals of the water vascular system.
What are the main characteristics and groups of echinoderms?
Echinoderms are invertebrates with an internal skeleton and a system of fluid-filled tubes called a water vascular system. There are four major groups of echinoderms: sea stars, brittle stars, sea urchins, and sea cucumbers.
What four purpose of an echinoderms water vascular system?
respiration, circulation, movement, and feeding
How do echinoderms use their tube feet?
Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.
