Much of the body structure of the sponge is dedicated to moving water through the body so it can filter out food, absorb dissolved oxygen, and eliminate wastes. WebGas Exchange in Platyhelminthes continued Since gas exchange occurs across the surface of the flatworm, surface area to volume ratio is relevant. A body plan that is extremely flat and thin is able to provide a large amount of surface area for diffusion relative to the volume of the animal. The thin body and large surface area for diffusion makes it possible for …
