Fish heart valve. Coloured scanning electron micrograph (SEM) of a view from the ventricle of the heart to the atrium in a Japanese pilchard (Sardinops melanostictus). Between the two chambers is a heart valve (centre), which prevents the back-flow of blood. The fish heart pumps deoxygenated blood to the gills where it is oxygenated and then flows to the rest of the body.
