WebbDescribe the gas exchange mechanism in flatworms. Multicellular organisms with a relatively small SA/V ratio (in comparison to the Amoeba) However, flat structure provides a large surface area and reduces the diffusion distance Simple diffusion is sufficient to meet the demands of respiratory processes WebbChapter 70 Respiratory Physiology: Gas Exchange Gas exchange at tissue level driven by partial pressures, occurs via simple diffusion DIFFUSION-LIMITED & … WebbIs diffusion the best method for gas exchange? Basic Principles of Gas Exchange Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. simon-stueart counseling service
