  • The respiratory system

    The respiratory system Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through…

Gills allow fish to breathe underwater. Respiratory mechanism in bony fish The fish draws oxygen-rich water in through the mouth (left). It then pumps it over gills so oxygen enters the bloodstream,…
