 do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system supports all these functions. They filter food particles out of the water flowing through them.

The excretory opening of Porifera is osculum.  

Explanation:  

  • The osculum is present in the Porifera’s excretory opening, and these help in absorbing ammonia, carbon dioxide, and water through the process of diffusion.
  • When mineral particles get stuck in this process as they are too big to pass on through the opening, they are left behind in the water.
  • The excretory system of the Porifera is dependent on a water flow system.
