Webcheap wedding venues in michigan » eastern randolph football score » how are fish gills adapted for gas exchange. sierra pacific industries news Uncategorized. 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…

The blood vessels are in very close proximity to the lamellae, allowing a short diffusion pathway. A fish also utilises a ... WebWhy are gills so feathery? To get enough oxygen the fish must make water flow across its gills. The water gives oxygen to the blood in the gill filaments and receives carbon dioxide in exchange. Finally, the water passes out from under the operculum. The fish’s gills are feathery, made of gill filaments which give them a large surface.
