Flatworms are small, literally flat worms, which ‘breathe’ through diffusion across the outer membrane. The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

Web1 jan. 2013 · Gas exchange in anoxia-paralyzed insects must be accomplished primarily by diffusion. Even very large insects weighing multiple grams can recover from exposure to anoxia when returned to room air, demonstrating that they can attain sufficient oxygen delivery to initiate movement by diffusion ( 24 ). WebFlatworms move in two ways: 1) with their cilia and 2) through the usage of muscle contractions. Cilia, tiny, moving bristles, join with muscles under the flatworm's skin to help them move about. The flatworm uses its muscles to change the pressure of the fluid in its body (Cambell, 2008). how to spoof callWebThey have a flat body because they do not have a coelom or even a pseudocoelom. They also lack a respiratory system. Instead, their cells exchange gases by diffusion directly with the environment. They have an incomplete digestive system.

"WebMulticellular Organisms are bigger than Unicellular organisms. This makes efficient diffusion of gases more difficult. However, if they are small, or large but very thin (like the flatworms, Platyhelminths), the outer surface of the body is sufficient as an exchange surface because the surface area to volume ratio is still high.
