Fishes breathing organs
Did you know?
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… WebThese fishes have evolved a variety of air-breathing organs, most of which are outgrowths or pouches from the pharynx, branchial (gill) chamber, or digestive tube. Some catfishes ( Clarias and Heterobranchus) of Asia and Africa have branched respiratory structures extending above the gill chambers; others ( Heteropneustes) have elongated ...

They have special organs called gills that help in breathing. Gills are feathery organs projected out of the skin, richly supplied with blood vessels and are covered with gill slits. The fish takes water through the mouth and forces carbon dioxide out of the gills.
WebDec 24, 2024 · It is quite common to see a labyrinth fish rise to the top of the tank and gulp air from the surface of the water. The air is forced into the labyrinth organ, to allow the oxygen to be absorbed. Within the labyrinth, …
WebFish take in oxygen-rich water via their mouths and pump it over their gills. When water moves over the gill filaments, the blood within the capillary network takes up the dissolved oxygen. Then, the circulatory system … rayman exportsWebMolecular and developmental evidence suggests that these fish had two separate organs for breathing – a gill system for extracting oxygen from water, and lungs for taking in atmospheric air – and that the two eventually merged together. ... an organ used for buoyancy in most bony fishes.
