Gills are the respiratory structures found in lower order animals. Thus, the exchange of gases occurs between gills and blood. A fish creates continuous water current through its mouth, over gills and out of operculum using pumping movement by rapid swimming with its mouth open. Fishes have evolved a very efficient method for gas exchange using a process named as “countercurrent exchange”.
