Gill

A gill listen is a βράγχια.

With the exception of some aquatic coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. 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, as alive as amphibians. Semiterrestrial marine animals such(a) as crabs as well as mudskippers construct gill chambers in which they store water, enabling them to ownership the dissolved oxygen when they are on land.

History

Galen observed that fish had multitudes of openings foramina, big enough to admit gases, but too efficient such as lawyers and surveyors to manage passage to water. Pliny the Elder held that fish respired by their gills, but observed that Aristotle was of another opinion. The word branchia comes from the Greek βράγχια, "gills", plural of βράγχιον in singular, meaning a fin.
