Preferred Label : gill;
Uberon definition : Anatomical surface structure found in many aquatic organisms. It is a respiration
organ whose function is the extraction of oxygen from water and the excretion of carbon
dioxide. The microscopic structure of a gill is such that it presents a very large
surface area to the external environment. Gills usually consist of thin filaments
of tissue, branches, or slender tufted processes which have a highly folded surface
to increase surface area. A high surface area is crucial to the gas exchange of aquatic
organisms as water contains only 1/20 parts dissolved Oxygen compared to air. With
the exception of some aquatic insects, the filaments and lamellae (folds) contain
blood or coelomic fluid, from which gases are exchanged through the thin walls. Oxygen
is carried by the blood 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, and amphibians.;
