Sponges are a type of aquatic animal whose body is covered in tiny pores called ostia. The ostia allow water, oxygen, and other nutrients to flow into the sponge's body, and for waste products like ammonia and carbon dioxide to exit their body. The respiratory system of a sponge is based on the process of diffusion.
