Fish gills adaptation for gas exchange
WebA fish had gills, made up of gill filaments containing lamellae, which provide a very large surface area for oxygen to diffuse out of the water as it moves over them. The blood … 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…

This means the water flows … WebOther fish species do not possess any lungs, but may use their swim bladders for gas exchange, or rely on diffusion through their skin and gills for oxygen intake. The Lungs of Fish: An Overview. The lungs of fish are known as modified swim bladders, which serve a dual purpose. In most fish, the modified swim bladder is used for buoyancy in ...
WebApr 11, 2024 · Through a process called gill respiration, fish are able to take in water through their mouths and pump it over their gills. Inside the gills, tiny blood vessels called capillaries absorb the oxygen from the water and transport it to the rest of the fish's body. The carbon dioxide produced by the fish is then released back into the water ...
WebSep 15, 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.
