They connect the radial canal to the ampullae in the water vascular system.
The radial canal is the channel for water flow throughout the body of most fish species. According to Biologists, the canal is lined with choanocytes which allows for water to pass.
the stone canal connects the madreporite to the ring canal and the ring canal allows water to flow into the radial canals, just tubes...
radial symmetry
The medusa, sea anemone, and polyp all have radial symmetry.
that's easy it goes through the sieve plate, to the stone canal, then into the ring canal , to the radial canal and out the tube feet which are also used for respiration :)
what is the function for central canal
An apopyle is a pore through which water passes out of a radial canal or flagellated chamber of a sponge.
In a starfish, the ambulacral ossicles are little calcified bony plates covering the radial canal.
Water comes into the system via the madreporite. It is then circulated from the stone canal to the ring canal and into the radial canals. The radial canals carry water to the ampullae and provide suction to the tube feet. The tube feet latch on to surfaces and move in a wave, with one body section attaching to the surfaces as another releases.
The auditory canal is lined with sebaceous or ceruminous glands
The main function for central canal is to carry all the blood vessels and nerves in the body. It is found in every bone that is in the human body.
