WebMar 31, 2024 · Fish use specialised surfaces called gills to carry out gas exchange. Gills are highly folded, giving them a large surface area and maximising the efficiency of gas exchange. The water that passes over the gill lamellae flows in the opposite direction to the blood within the gill lamellae. WebWhy are gills so feathery? To get enough oxygen the fish must make water flow across its gills. The water gives oxygen to the blood in the gill filaments and receives carbon dioxide in exchange. Finally, the water passes out from under the operculum. The fish’s gills are feathery, made of gill filaments which give them a large surface. WebIn fish, gill lamellae are used to increase the surface area in contact with the environment to maximize gas exchange (both to attain oxygen and to expel carbon dioxide) between the water and the blood. In fish gills there are two types of lamellae, primary and secondary. … dick\\u0027s sporting goods mall of ga
