The system is composed of canals connecting numerous tube feet. Echinoderms move by alternately contracting muscles that force water into the tube feet, causing them to extend and push against the ground, then relaxing to allow the feet to retract.
Water enters madreporite and flows through the stone canal and then enters the circular ring canal. Water then is separated into five radial canals that branch into double rows of bulblike structures called ampullae, which are on each side of the ambulacral ridge. The ampullae are connected to suckerlike podia, the entire structure is called a tube foot. Contraction of the ampullae causes the podia to stretch as water is brought into them. This whole process allows for movement, and is quite powerful but extremely slow.

What Interconnected canals and hollow tube feet work together in sea star's?
Water-vascular system.
Interconnected canals and hollow tube feet work together in sea star's what?
Interconnected canals and hollow tube feet work together in a sea star's water vascular system, which helps with movement, feeding, and respiration. Sea stars use water pressure to extend and retract their tube feet, enabling them to grip surfaces and capture prey.
What are the components of a vascular system in plants?
The components of a vascular system in plants are xylem, which transports water and minerals from roots to leaves, and phloem, which transports sugars and other organic compounds throughout the plant. These two tissues work together to provide support, transport nutrients, and facilitate growth in plants.
Which feature would you find on an echinoderm-?

What are the two main structural axes of a vascular plant?
The two main structural axes of a vascular plant are the shoot system and the root system. The shoot system includes the stems, leaves, flowers, and fruits, while the root system anchors the plant in the soil and absorbs water and nutrients. These two axes work together to support the plant's growth and function.
More answers on how does the cardio vascular system work?
Pumps blood around the body, to supply the tissues with oxygen and nutrients and to transport waste products away from these tissues.
What are tube feet on a star fish?
Tube feet are a series of small tubular projections that can be find on all echinoderms, including the star fish. By pumping fluids in and out of these tubes, hydraulic pressure is created that can be used to grip onto a surface or circulate materials around the feet. In star fish, tube feet are often used as suction cups to keep a grip on the environment and prevent being swept away by undersea tides.
What system is star craft 2 for?
Star craft 2 is for the PC system, different types will work with MAC but you have to buy the compatible software.
Why are vascular plants better suited to live in dry areas?
Vascular plants, which include ferns, flowering plants and seed plants, have adapted to be able to transfer nutrients farther than nonvasculars, which allows them to grow taller and larger. Vascular plants also have a better root system to absorb minerals to support their larger size. if you don't think that a lot of flowering plants would be considered large, compare it with moss. moss grows very low to the ground because it cann't support a larger body.
Which tissue in the cardiovascular system work together to pump blood?
The heart is the pump of the cardio vascular system, and the arteries and the veins help to circulate the blood around the body
What is a vascular surgeon DO?
they work with the cardiovascular and circulatory systems
What are blood vessel size directly and indirectly controlled by?
The vascular system signals for blood vessels to constrict or dilate. The nervous system, such as the spine, and the brain, work together to help blood vessels respond accordingly.
