? Lungs are organs that many animals have and belong to respiratory organs. As a respiratory organ, the respiratory efficiency of the lungs is relatively high. However, not all animals use lungs to breathe, some of the more advanced animals have this more advanced structure, such as reptiles, birds and mammals. Fish are relatively inferior animals, and they do not have the more advanced structure of lungs. Loach belongs to the class Osteichthyes, which is a kind of fish. Like other fish, they have no lungs and do not breathe with lungs. Their main respiratory organs are gills, and most fish breathe through gills.
with? As mentioned above, loach has no lungs, they have gills, and like other fish, they mainly breathe with gills. Misgurnus anguillicaudatus is a special fish, which is also reflected in the respiratory organs. Gills are the only respiratory organs in most fish, but loaches have not only gills, but also auxiliary respiratory organs, including their skin and intestinal walls.
When loaches are in the water, they breathe mainly through their gills. However, when there is insufficient oxygen in the water, they will jump out of the water voluntarily, or when the loach leaves the water, they will use the intestinal wall to breathe. At this time, the loach will directly swallow the air, absorb the oxygen, and the exhaust gas will be discharged through the anus. Because loaches have this characteristic, they can survive for a period of time out of water, but they need to live in wet places, otherwise their normal breathing will be affected.
