WebLungs in humans and gills in fish use blood capillaries to remove the oxygen they need and excrete waste carbon dioxide. Fish have adapted to absorb oxygen from the water they filter, whereas humans and insects on land diffuse air which is easier and more efficient. All of these animals use. different ways to carry out gas exchange, 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.

WebFish 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 gill filaments have many protrusions called gill lamellae. One of the ways in which gas exchange is carried out efficiently is by the countercurrent flow principle. Web17 jan. 2024 · But instead of lungs, they use gills. Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries.
