WebDiffusion occurs in fish mainly in their gills, where oxygen and carbon dioxide are exchanged with water. Additionally, diffusion can occur in their skin and other tissues. More 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 netw…
WebApr 6, 2024 · Fishes exchange gasses by pulling the oxygen-rich water content through their mouth and by pumping it across the gills. Once the oxygen has been absorbed by the gills, the remaining water is thrown out. Bony fishes have only one-gill openings, but some fishes like lampreys and sharks have multiple gill openings. WebGenerally, fishes use gills and tetrapods use lungs, although the distinction is not absolute Through ventilation of the organs of the respiratory system, gaseous exchange can occur Ventilation of respiratory structures depends on ram ventilation - forward momentum contributes to flow of water across the gill membranes
