What is Gill?
[[File:Smooth Newt larva (aka).jpg|thumb|Gills seen on a [[newt]] (a type of [[amphibian]])]][[File:Tuna Gills cut out.jpg|thumb|Gills of a [[fish]]]] '''Gills''' are what [[fish]], [[amphibian]]s, and some other [[animal]]s use to breathe in water. They have feathery parts which cause water to move across the animal's body, which contains dissolved [[oxygen]], after the animal has swallowed the water. The oxygen is absorbed into the animal's [[blood]], causing [[carbon dioxide]] to move out of the animal's blood and into the water through the gills. Fish and [[frog]] gills are hidden on the sides of their heads. [[Shark]]s have many gills slits on their necks. Baby [[salamander]]s have gills that stick out like leaves from their heads. In [[mushroom]]s, '''gills''' are the [[spore]]-bearing structure in [[Agaricales|agarics]] (gilled mushrooms) while fish and some young amphibians use them to get oxygen others breath. Some insects that live in water have a '''plastron''', which is a kind of gill. It is a patch of special hairs that keeps the water away from the insect's [[spiracle]]s. This allows them to continue to take in oxygen and remove carbon dioxide while they are under water. {{commonscat|Gills}} {{Biology-stub}} <!-- interwiki -->[[Category:Animal anatomy]] [[Category:Anatomy of the respiratory system]]
