Fish gills adaptation for gas exchange
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… WebAquatic arthropods generally possess some form of gills in which gas exchange takes place by diffusing through the exoskeleton.Others may breathe atmospheric air while …
