WebJun 18, 2024 · The thinness of the animal's body makes gas exchange without special structures practical. Digestion Planarians are carnivores and obtain their food by predation or scavenging. The muscular pharynx extends through the mouth to pick up food and then withdraws into the body. The pharynx leads to a branched digestive tract. WebDefine gas exchange - Have a large surface area to v ratio so rate of exchange satifies the organisms needs - Have a short diffusion pathway- so be thin - Be permeable-->resp gases diffuse easily - Have a mechanism … WebMar 25, 2024 · How does flatworm adapted for gas exchange? 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. tall man from cornwall poem
