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 ...
2 sty 2023 · Fish gills are crucial respiratory organs that enable fish to breathe underwater by extracting oxygen dissolved in water and eliminating carbon dioxide from their bodies. Typically situated on each side of the fish’s head, these gills are shielded by a bony plate known as the operculum.
Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill chambers in which they store water, enabling them to use the dissolved oxygen when they are on land.
12 wrz 2024 · Gill, in biology, type of respiratory organ found in many aquatic animals, including a number of worms, nearly all mollusks and crustaceans, some insect larvae, all fishes, and a few amphibians. The gill consists of branched or feathery tissue richly supplied with blood vessels, especially near the.
18 lip 2017 · Fish Gills. Fish breathe through gills instead of lungs. Just like all other animals, fish need oxygen to survive. Because they live in water, they have evolved gills which enable them to remove dissolved oxygen from water. Most fish have four gills on both sides of their head.
21 maj 2024 · Fish are aquatic vertebrates that typically have gills, fins, and a streamlined body. They inhabit diverse environments, from freshwater rivers and lakes to salty oceans and deep seas.
17 sty 2020 · Fish aren’t the only undersea organisms to use gills, however. Mollusks and crustaceans also have gills that operate the same way by pulling oxygen out of the water as it runs over the gills. Some animals even display their gills outside of the body: the name “nudibranch” (commonly known as sea slugs) comes from Greek and Latin words ...
