sponges let the water enter through the canal and circulates all over the body.
Apopile and prosopiles are special pore present in canal system of sponges , through which water circulates from incurrent canal flagelated channels and excurrent canal of sponges .
it is a canal system found in sponges(porifera phylum). its example is Leucon. the intresting fact is that this is the only water canal system present in sponges which do not have SPONGOCOEL. in this water moves inside through ostiathen to incurrent canal then prosodi then flagellate cells and then to apodi then to excurrent canal and den to osculum then out..!!

Sponges are bottom-dwelling creatures that attach themselves to something solid, such as a rock. They rely on the system of the water canal to deliver food and oxygen to them. Sponges consume plankton.
They connect the radial canal to the ampullae in the water vascular system.

The alimentary canal and the accessory organs
The alimentary canal and the accessory organs
the stone canal connects the madreporite to the ring canal and the ring canal allows water to flow into the radial canals, just tubes...
Sponges do not have blood. They do not have a circulatory system either.
