It’s all about partial pressure. In a fish, oxygen moves from the surrounding water through the gills to the blood and finally the tissues. At each step, the oxygen level becomes lower — otherwise the oxygen wouldn’t diffuse. This graph redrawn from Eckert & Randall (14-13).

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… Web26 de jun. de 2014 · The gills of fish remove oxygen from water with extreme efficiency because water flows countercurrent to capillary blood flow. “Water flow over the secondary lamellae is countercurrent to capillary blood flow, resulting in extremely efficient oxygen extraction.
