Detailed explanation-1: -A bony fish’s heart has two chambers: an atrium and a ventricle.
Detailed explanation-2: -Fishes have only two chambers of the heart-the atrium and ventricle. The oxygenation of blood happens through the gills.
Detailed explanation-3: -Fish and Insect Hearts Fish hearts have just two chambers, an atrium and a ventricle (Figure 1).
Detailed explanation-4: -Complete Answer:-Fishes have a two-chambered heart. The heart consists of an atrium and a single ventricle. The atrium receives blood and the ventricle is responsible for pumping it. The circulation in fishes is also a single circulation in a single direction-unidirectional flow.
Detailed explanation-5: -In fishes and reptiles, there is mixing of blood (oxygenated and deoxygenated) due to less number of chambers in the heart. In humans, there is a separation of pure and impure blood flow in separate chambers for more efficient transport and faster energy production which is needed for body temperature maintenance.
