Most fish breathe through gills, also known as gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head.
The heart of the fish has two cavities, an atrium and a ventricle - and through it only unoxygenated blood circulates. After passing through the heart, unoxygenated blood goes to an artery and into the gills where it receives oxygen gas. This now oxygenated blood is distributed to all organs of the animal's body.
