Oxygen supply to, and carbon dioxide removal from, vertebrate respiring tissues take place through a set of serially arranged anatomical compartments, either by molecular diffusion or by mass convection via carrier fluids. Respiratory organs are designed in such a way as to optimize the efficiency of gas transfer according to particular constraints set out by ambient media and/or animal physiology.
