What Is a Respiration Organ?
An organ that is specially differentiated for external breathing. In other words, it is the organ that restricts the breathing surface to a local area and develops as an adaptive structure. Animals with simple systems or slow-moving animals often perform skin respiration and intestinal respiration without special respiratory organs. Even if there are differentiated respiratory organs, they are often carried out with skin respiration and intestinal respiration. The salamander gill is a specialized differentiation organ, in addition to other physiological functions, such as the petaloid gills of the petal gills and the side feet of the hairy class. Common features: (1) thin wall and abundant blood supply (2) due to protrusions. The total surface area is significantly enlarged, such as folds and branches, which improves the gas exchange efficiency between the internal medium and the external medium.
