Web10 dec. 2024 · So, fishes need a special system to get their oxygen. Fishes do not have lungs like other animals. Instead, they have gills. Fish get water through the gills. Then, the gills extract oxygen from the water. Also, gills let the water take the carbon dioxide out of their bodies, and that’s how they breathe. WebGas-exchange efficiency is therefore dependent on the rate at which water flows across the gills, and different species have developed a wide range of strategies to control this. Buccal-opercular pumping is the most common ( Fig. 25.4, C ) in which the entrances to the mouth and operculum are opened and closed alternately and the muscular walls of the cavities …
