Ostia are small pores found on the surface of a sponge that facilitate water flow into its body. They allow water, which carries oxygen and nutrients, to enter the sponge's internal cavity, where it is filtered for food particles. These openings are crucial for the sponge's filter-feeding mechanism, enabling it to sustain itself in its aquatic environment.

How does the sponge keep water flowing through its ostia and out through the osculum?
The sponge works like a chimney. Water rushes in from beneath through ostia and comes out ffrom osculum. This action is continuously controlled by wholly or partially closing the osculum and ostia and varying the beat of the flagella, and the pores may shut if there is a lot of sand in the water before it could block the system.
