Sponge - Filter Feeding, Skeleton, Reproduction: Sponges are primarily filter feeders They lack respiratory organs and excretion occurs through the oscula and the surface of the sponge

Because each cell exchanges oxygen and carbon dioxide and discharges waste products into the seawater, a sponge has no respiratory, circulatory, or excretory system
- Porifera - The Excretory System
Porifera is the latin name that came from the pores on the surface of the sponges All types of sponges have the same excretory system The sponges' cells absorb oxygen by diffusion from the water flow system, into which carbon dioxide and other soluble waste products such as ammonia also diffuse
- Phylum Porifera | CK-12 Foundation
Sponges do not possess specialized respiratory or excretory organs Instead, they rely on simple diffusion across their cell membranes to exchange gases and remove waste
- Spongia officinalis Linnaeus - ArcGIS StoryMaps
Excretory System This process begins with water flowing into the sponge through the ostia and moving through the internal canal system before exiting through the osculum As the water circulates through the body, dissolved oxygen diffuses into the cells, while metabolic wastes such as carbon dioxide diffuse out into the passing water
