How fish gills are adapted for gas exchange
WebDescribe and explain how fish are adapted for gas exchange. Fish gills are made up of thin plates called gill filaments, which are covered in structures called lamallae. Both the gill filaments and lamellae provide a large surface area for gaseous exchange, increasing … 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…

Web15 sep. 2024 · Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing counter-current exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. What type of gas exchange do fish use?
