उत्तर
Pisces only
In Pisces, the heart does not pump oxygenated blood to different parts of the body. This is because Pisces have a two-chambered heart with one auricle and one ventricle. Since both the auricle and ventricle remain undivided, only deoxygenated blood passes through it. The deoxygenated blood then enters the gills for oxygenation from the ventricle.
