Cutaneous respiration
Cutaneous respiration is the breathing that used skin.
Because every field is used for every industry by different uses, I comment on this word each.
I am considered to be "external respiration performed with a surface of a body with the cutaneous respiration (cutaneous respiration) in biology (Iwanami biology dictionary" cutaneous respiration ).
It is originally said that the body surface has a function to pass oxygen.
The animal has many things comprising the organ for gas exchange with the outside the body, but there is the thing which does not have such a structure.
It is said that the animal which does not hold special respiratory organs will depend on cutaneous respiration.
For example, it is said that it is performed with an earthworm and a leech of the Annelida, a broom insect or the sea moss of the feeler animal.
Because there is enough gas exchange only by cutaneous respiration with the particularly small animal, there are many cases that do not have specific respiratory organs.
There are many animals which even a thing having respiratory organs in its own way makes cutaneous respiration.
Even if it "is thought that the soft thing of the skin does the cutaneous respiration of the fixed quantity", it is said.
I tend, and the cutaneous respiration that used skin and a mucous membrane performs whether amphibians and the reptiles use it together with breathing in lungs with the vertebrate.
There is the part that is rich in the capillary to a key part and an inner wall of the cloacae, and this part participates in gas exchange.
It is said that what can use cutaneous respiration together with pulmonary respiration has a big place by the structure (one treacherous thoughts bunch cardiac ventricle) of the heart that the blood of the vena cava mixes with a pulmonary vein each other.
But I am different, and, for example, the ratio is high so that temperature is low in the case of an eel, and I am equal to or less than 10 degrees Celsius, and the ratio (the ratio of the oxygen intake) of the cutaneous respiration to occupy for all breathing reaches the ratio of the oxygen intake by the cutaneous respiration than 60% for all breathing by the kind of the creature and a temperature condition when cutaneous respiration is used together with breathing by respiratory organs.
（It is said that this is called the reason why the land can crawl up an eel in the night）.
It is different whether it is not so, and cutaneous respiration is around 30-50%, but, in the case of the frog, it is said that cutaneous respiration becomes 70% while I hibernate generally whether you are hibernating.
For example, with birds and the mammals, the ratio of the cutaneous respiration says less than 1% with a dove and the Homo sapiens low.
