Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia. Each filament contains a capillary net… WebFish live in water, which has a low concentration of oxygen. This means lots of water has to flow over the gas exchange surface for the fish to take in enough oxygen. Water is also harder to ventilate than air because it is …
