WebThe gas exchange system in birds exhibits many unique features that endow them with the enhanced capacity for oxygen transport that is believed to underlie the evolution of the increased cardiorespiratory performance required to support flight. Bird lungs are rigid and are ventilated by an extensive air sac system that isolates the expansible ... WebGas Exchange in Fish. The water surrounding a fish contains a small percentage of dissolved oxygen. The fish uses a special gas exchange organ (gills). It has a large surface area and a short distance for gas exchange to the blood capillaries. Water flows over the filaments, and oxygen can diffuse down its concentration gradient the short ...
WebGas exchange is a fundamentally important function of the lung. The same basic mechanisms of diffusion and convection govern gas exchange and gas transport in all mammals. The demand for O 2 set by the body varies allometrically with changes in body size, so that smaller mammals have a higher mass-specific demand than do larger … WebGas Exchange.
