The Essential Rhythm 2/20/22: Breathing from water

Producer/Host: Sarah O’Malley

This episode elaborates on the simple gas exchange mechanisms of sponges, cnidarians and flatworms. These organisms lack specialized gas exchange organs, instead relying on simple diffusion across the body wall. This limits their body shape and structure as a trade off for reducing the diffusion distance gasses pass through.
