Fish exchange surfaces
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 … See more Air breathing fish can be divided into obligate air breathers and facultative air breathers. Obligate air breathers, such as the African lungfish, are obligated to breathe air periodically or they suffocate. Facultative air … See more Lampreys and hagfish do not have gill slits as such. Instead, the gills are contained in spherical pouches, with a circular opening to the outside. Like the gill slits of higher fish, each pouch … See more Although most fish respire primarily using gills, some fish can at least partially respire using mechanisms that do not require gills.

WebIn this video we continue our discussion about exchange surfaces, focusing on exchange of gases in the leaves of plants, and through the gills of fish.Contac... WebFish have filaments along their gills where gas exchange takes place. These greatly increase the gas exchange surface area as they are folded up. Mammals have increased their gas exchange surface area by having alveoli at the end of the broncheoles. These little sacks mean that the gas exchange surface is nearly as big as a tennis court.
WebThis means the water flows through the gills in one direction, allowing for more efficient gas exchange than if the water had to go in and out the same way. This is important for fish becaus of the low oxygen concentration in … WebJun 8, 2024 · Gills are found in mollusks, annelids, and crustaceans.
