Let's take a sponge for an example. A sponge's function is to what? Be aerodynamic? No. It's porous STRUCTURE allows passage of organisms or cells to transport whatever it is they need to transport to wherever it is they need to go. It's function would be to protect those things during its path of travel. Done. I hope that makes sense.

Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
The osculum is an excretory structure in the living sponge, a large opening to the outside through which the current of water exits after passing through the spongocoel. Wastes diffuse into the water and the water exits through the osculum at a velocity of nearly 8.4 cm/second, carrying away with it the sponge's wastes. The size of the osculum is regulated by the myocyte. Its size, in turn, determines the amount of water flowing through the sponge.
The spicule in a sponge is its skeleton. It provides strength in the sponge.

According to my calculations, a sponge is similar to a fish but is not quite a fish.
They improve both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a rapid expulsion of carbon dioxide and other waste products.

The epidermal cells of sponges are responsible for cell adhesion and maintenance of their shape and structure. The epidermis is composed of pinacocytes (epidermal cells) which are flattened cells in the sponge's body wall.
Because they both absorb in the same way
